Hi EE,

I have a problem with a form that contains a list box and some option boxes.

In my code, I am trying to compare two values:

Column C in my worksheet
Column(0) of my listbox

When the form opens, I select one or multiple rows in my listbox. Then, I select a code to apply. After doing so, I click the process button and for each of the rows selected in my listbox, I need to update the respective rows in my worksheet (column I) with the code that was selected in my form.

In the code I have, it works for one, but not for any more and I suspect it is an issue with the way I have written it.

Private Sub cmdProcess_Click()
    
Dim wkb As String, i As Integer, response As Integer, msg As String, title As String, style As String, _
    intcounter As Integer, oCtrl As Control, k As String

'check for list box selection
If Me.lstTrans = vbNullString Then
    'if nothing was selected, tell user and let them try again ->>
     Exit Sub
Else
    'only controls
    For Each oCtrl In frm_ledger_coding.fra1.Controls
        'only option buttons
        If TypeName(oCtrl) = "OptionButton" Then
            'which one is checked?
            If oCtrl.Value = True Then
                'what's the tag?
                k = oCtrl.Tag
                Exit For
            End If
        End If
     Next
    'specifying cunter to start from row 2
    intcounter = 2
    If k = "" Then Exit Sub Else
    'specifying list selection counts
        For i = 0 To lstTrans.ListCount - 1
            If lstTrans.Selected(i) Then
                With ActiveWorkbook.Worksheets("Import")
                    'Range H being the amount which always have a value
                    While .Range("H" & intcounter).Value <> ""
                        'compare the key in column c with the list value in column 0 (bound column)
                        If .Range("C" & intcounter).Value = lstTrans.List(i) Then
                            Range("I" & intcounter).Value = k
                        End If
                    intcounter = intcounter + 1
                    Wend
                End With
            End If
        Next i
End If

End Sub

Hi there,

Thanks for sorting this. I thought I had it sorted but was badly mistaken.

Just for clarity, in line 24, we specify intcounter as 2, then in line 29 we do it again. Can you explain why it is like this?

It's the main reason your first script LOOPED properly, but returned only one result. Because by the end of line 37 (your old code), the while loop starting at 31 will ALWAYS return nothing and not go through the while loop. The intcounter is stuck at 80, which is the last line of your whole sheet having an empty cell. If you want to loop something inside another loop, you have to reset the conditions just before you enter the loop.

Hi. Thanks for outlining that. I was wondering why that was. Now I understand because it is a loop inside a loop which makes absolute sense. Cheers, :)
