I am new to VBA and have been trying to develop a form in excel to do some calculations.  I want to use a combo box with text options that will be assigned to a variable in the form of an interger.  I want ALL of my options and variable contained within the code.  I do not want to reference lists or values from the spreadsheet for my list...I want to have my form ask for multiple conditions and calculate my answer and return a single decimal number back to the spreadsheet...I have the form i have the list for the combo box defined and it works. However i can't figure out how to pass these values into a variable and them manipulate them..

Hello ToddHawley4984,

here an example piece of code to show you how to load a combobox based on the content of a variable. In this example I used an array called arr.

this arr contains values.
I place the code in Userform_Initialize macro so the combobox will be filled when userform is opened.
Place this code behind the userform code pane.

I hope this works for you
regards,
Jeroen
Private Sub UserForm_Initialize()
Dim arr As Variant
arr = Array("Value1", "Value2", "Value3", "Value4")
ComboBox1.List = arr
End Sub

Actually this code was an alternate way of doing what i had already done...In the example i have posted i have the following options in my combobox...They show up like they are suppose to...What i can't figure out is how do i for example assign what i pick in the drop down box to the STRING variable "SF1" that i have declared?  Each string will have a corresponding Decimal coefficient in a hydrology calculation i am working on. So my plan was to assign a value of 1-11 to each text string.then use an if statement to determine what coefficient should be passed into the equations i'm using...I'm basically just not makinig the link between what i pick in the box and assigning it to a variable that i can then reference from other section of the code. Also if a variable is defined what determines if it is a global variable or a variable only used in the current Sub?  I'm just learning this today for the first time...I'm quite fluent in excel but not VBA/VBE
'Userform1 code
Sub InitializeMEComboSF1()
Dim SF1 As String
ComboSF1.AddItem "Woods Light Underbrush"
ComboSF1.AddItem "Woods Medium Underbrush"
ComboSF1.AddItem "Woods Heavy Underbrush"
ComboSF1.AddItem "Grass - Short Grass Prairie"
ComboSF1.AddItem "Grass - Dense Grasses"
ComboSF1.AddItem "Grass - Bermuda Grass"
ComboSF1.AddItem "Natural Range"
ComboSF1.AddItem "Smooth Surfaces (concrete,asphalt,bare soil)"
ComboSF1.AddItem "Fallow (no residue)"
ComboSF1.AddItem "Cultivated Soils <or= 20% Residue Cover"
ComboSF1.AddItem "Cultivated Soils > 20% Residue Cover"
ComboSF1.Value = "Select A Land Condition For First Segment"
 SF1 = ComboSF1.Value

If you want the value to be returned in a variable like
"Woods Medium Underbrush" would be the second item in the list and the variable should be filled with: 2

then use this:
SF1 = ComboSF1.Listindex +1

(you have to add 1 because comboboxes starts counting at 0.

In my example code it would be something like
Private Sub UserForm_Initialize()
'Sub InitializeMEComboSF1()
Dim arr As Variant
Dim SF1 As String
arr = Array("Woods Light Underbrush", "Woods Medium Underbrush", _
"Woods Heavy Underbrus", "Grass - Short Grass Prairie", "Grass - Dense Grasses", _
"Natural Range", "Smooth Surfaces (concrete,asphalt,bare soil)", "Fallow (no residue)", _
"Cultivated Soils <or= 20% Residue Cover", "Select A Land Condition For First Segment")
ComboSF1.List = arr
 
 SF1 = ComboSF1.ListIndex
 MsgBox SF1
 
 
End Sub

Well u can use the code that you want to use...all u need to do is this...

ComboSF1.Style = fmStyleDropDownList

and remove the

ComboSF1.Value = "Select A Land Condition For First Segment"
 SF1 = ComboSF1.Value

this will do the trick for u...

I think this is what i'm looking for...however Im a little confused about the difference between the "Private Sub" and "Sub" I assume this has to do with public or private variables...but i'm not sure.  I has the following code in a module. I have in my spreadsheet a button which executes this macro...However if my initialized combo boxes are "private Sub" then this module can't find them...

Sub ShowUserform1()
UserForm1.InitializeMeComboSF1
UserForm1.InitializeMeComboSF2
 
UserForm1.Show
End Sub

Since i'm trying to pass values within the code and not back to excel til the end, should i be using functions instead of sub procedures?
