Question

Linking Function criteria into Evaluate function in VBA

Asked by: doongie

Hi All,

I'm writing a function and want the a Currency to be specified as part of the criteria. The original Arrary formula is too long for Excel to cope with so have used EVALUATE in VBA. This is what I have so far however whenever I put anything but "USD" i get an error. Have tried using named ranges etc but can't seem to put anything but "USD" text in there to make it work

Thanks
Carl

Function MyFunction(COUNTRY as Variant)
 
    Dim RateA As Variant
    Dim FXTYPE As Range, RATE As Range, SPOT As Range
    
    Set FXTYPE = Sheets("Sheet1").Range("FXTYPE")
    Set RATE = Sheets("Sheet1").Range("RATE")
    Set SPOT = Sheets("Sheet1").Range("SPOT")
 
       
    vFX = [=if(FXTYPE="USD",1,0)] 'I want to remove "USD" and link it to the COUNTRY  
    vRateA = [=if(RATE="A",1,0)]
    vSPOT = Range("SPOT")
 
 
RateA = Application.SumProduct(vFX, vRateA, vSPOT)

Im not sure if this works as I couldn't get the function work.
If it currently works for you and you want to add the value how you call the function then it might be something like:

vFX = [=if(FXTYPE=COUNTRY,1,0)]

 

by: doongiePosted on 2007-11-18 at 07:08:40ID: 20307681

Yes that's what Ive been trying.

If I don't use the shorthand Syntax and set i to a value I get a result but I haven't managed to be able to get it to work for a range for text??
   
    i = 3
   vFX = Evaluate("=if(FXTYPE=" & CStr(i) & " ,1,0)")

 

by: roos01Posted on 2007-11-18 at 07:25:06ID: 20307743

What is the value you enter in the function?
If it is an number then you might try:
Function MyFunction(COUNTRY as Long)
instead of
Function MyFunction(COUNTRY as Variant)

 

by: doongiePosted on 2007-11-18 at 08:39:12ID: 20307986

No I want it to be text i.e. USD as in first example

 

by: roryaPosted on 2007-11-18 at 09:56:27ID: 20308258

Why are you using Evaluate? Why not just use:

If FXTYPE = COUNTRY Then
    vFx = 1
Else
    VFx = 0
End If

As I undertsand it, when replicating an array formula in VBA you use evalute. Using an If statement only returns 1 or 0 and doesn't "memorise" the result for that portion of the equation.

Is this correct??

 

by: roryaPosted on 2007-11-22 at 15:41:28ID: 20336679

Ah, sorry, I misunderstood the nature of your problem. You should be able to use:
Application.Evaluate("IF(FXTYPE=" & COUNTRY & ",1,0)")
Personally I would just loop through the array and populate another array accordingly.
Regards,
Rory

 

by: doongiePosted on 2007-11-26 at 03:30:52ID: 20349245

Hmmm...still have the same problem when I try that i.e. works for a value but not for text.

Can you expand on what you mean by looping thorugh the array??

Thanks
Carl

 

by: roryaPosted on 2007-11-26 at 12:33:26ID: 20352768

Try this:
Application.Evaluate("IF(FXTYPE=""" & COUNTRY & """,1,0)")

For looping you would do something like:
Dim varData
Dim lngIndex as Long
varData = Sheets("Sheet1").Range("FXTYPE").Value
for lngIndex = lbound(vardata,1) to ubound(varData,1)
    If varData(lngIndex,1) = COUNTRY then
        varData(lngIndex, 1) = 1
    Else
        varData(lngIndex, 1) = 0
    End If
Next lngIndex

Regards,
Rory

Thanks Rory - the extra quotation marks did the trick.
