Conditional logic not working

I have the following code that is not working.  I can't figure out why:

            SupplyODCheck = Replace(Nz(Me.ODSupply, 0), " Month", "")
            SupplyOSCheck = Replace(Nz(Me.OSSupply, 0), " Month", "")

            If SupplyODCheck >= 12 Or SupplyOSCheck >= 12 Then
                Me.YearSupply = True
            Else
                Me.YearSupply = False
            End If

When: SupplyODCheck  = 6, SupplyOSCheck  = 0

However each time it executes its hitting the first line and setting year supply True when its false.

how did you declare the variables "SupplyODCheck", "SupplyOSCheck"

dim SupplyODCheck as integer, SupplyOSCheck as integer

SupplyODCheck = cint(Replace(Nz(Me.ODSupply, 0), " Month", ""))
SupplyOSCheck = cint(Replace(Nz(Me.OSSupply, 0), " Month", ""))

They are Variants.... values come from a text box on a form.

You don't say what is in Me.ODSupply or Me.OSSupply
That doesn't make matters easy!
But you are using Replace
SupplyODCheck = Replace(Nz(Me.ODSupply, 0), " Month", "")
and that's a STRING function
Replace(expression, find, replace[, start[, count[, compare]]])
So, you are saying replace " Month" with ""
That still leaves you with a string of some sort, but I can't say because you haven't supplied the original values of Me.ODSupply or Me.OSSupply
Now you are checking against integers
If SupplyODCheck >= 12 Or SupplyOSCheck >= 12 Then

But the values in SupplyODCheck  and SupplyOSCheck are -- because of Replace -- strings
Option Explicit should be at the top of each module and each variable declaration should have a type
Dim SupplyODCheck as String

But, supply more code and more detail of the values involved
If set as a integer I get a type mismatch error when setting the value for SupplyODCheck  and SupplyOSCheck
Absolutely.
Replace is a string function.
What are you replacing?

@thandel

did you use the code i posted above?

The text boxes have values like "XX Month" where XX and be a value in .5 increments from 1 to 24.  I was just trying to pull the value from the text box to get the number by removing the " Month"... it is returning the correct value but I guess as a string???

Can then change the value from a string to an number? Or is there a better solution?

I'm sorry did you mean:

Option Explicit
Dim SupplyODCheck as String

Let me try.....

thandelAuthor Commented:
Using Option Explicit causes other errors in the code.  Am I understanding correctly?

Did you want them set as an integer?  I still have an error that was as well.

It doesn't cause them, it exposes them.
What Option Explicit does, is it REQUIRES you to declare all variables before you use them

works without Option Explicit:
'------------------------
sub MySub
x = 1
Msgbox x
end sub

works with Option Explicit
'--------------------
Option Explicit
sub MySub
Dim x as Integer 'declaration is required!
x = 1
Msgbox x
end sub

Its a type mismatch when the text box is null

Nick67Commented:
Now--to your problem
The text boxes have values like "XX Month"
Ok, replace is fine
dim SupplyODCheck as integer
dim  SupplyOSCheck as integer
SupplyODCheck = CInt(Replace(Nz(Me.ODSupply, 0), " Month", ""))
SupplyOSCheck = CInt(Replace(Nz(Me.OSSupply, 0), " Month", ""))

CInt will coerce the string from your Replace to an integer

Nick67Commented:

Where?
Nz(Me.ODSupply, 0) should take care of ODSupply (or OSSupply with its Nz) being null
0
 
thandelAuthor Commented:
Yes that is there the error is occuring, of type mismatch.  I know doesn't make sense given the NZ function.

Actually not null but "".

I tried this and it seems to be working:

            If Len(Me.ODSupply) > 1 Then SupplyODCheck = CInt(Replace(Nz(Me.ODSupply, 1), " Month", ""))
            If Len(Me.OSSupply) > 1 Then SupplyOSCheck = CInt(Replace(Nz(Me.OSSupply, 1), " Month", ""))

thandelAuthor Commented:
In fact this works with SupplyOD/OSCheck as a string:

            If Len(Me.ODSupply) > 1 Then SupplyODCheck = Replace(Nz(Me.ODSupply, 0), " Month", "")
            If Len(Me.OSSupply) > 1 Then SupplyOSCheck = Replace(Nz(Me.OSSupply, 0), " Month", "")

Revising my codes

dim SupplyODCheck as integer
dim  SupplyOSCheck as integer
SupplyODCheck = Cint(IIF(Me.ODSupply & ""="",0,Replace(Me.ODSupply, " Month", ""))
SupplyOSCheck = Cint(IIF(Me.OSSupply & ""="",0,Replace(Me.OSSupply, " Month", ""))

thandelAuthor Commented:
I'll use your code as an Int and using Cint as that seems the better  way of coding  :)

Nick67Commented:
Actually not null but "".
Now, look at your Nz()
Nz(Me.ODSupply, 0)
You are supplying 0, not "0"
And when you feed 0 into Replace - which is looking for a string! -- bad things happen, yes?
And look at the documentation for Replace

Return Values

Replace returns the following values:

If Replace returns
expression is zero-length Zero-length string ("")
expression is Null An error.
find is zero-length Copy of expression.
replace is zero-length Copy of expression with all occurences of find removed.
start > Len(expression) Zero-length string.
count is 0 Copy of expression.

So, yes, if you feed Replace "", you are going to get ""
And then you are going to try to coerce that to integer
Cint("") and that goes bang!

When you are taking user-generated input, and doing something with it, no matter what platform, it is ALWAYS a good idea to test what the user gives you for validity!

Your textboxes may need AfterUpdate events to kick the user in the teeth if they enter garbage, or this procedure you've got should kick out if the inputs are bad.  GIGO.
