Pulling data into a textbox from spreadsheet

[eklarsen]

I have a multipage userform that has several drop down boxes that the user needs to populate (name, month etc..) from that I have text boxes that I want to populate from another spreadsheet located in the same file.
I need to use an If-then because I want it too look until it finds a match to the month and then bring in column 3.
I have the textbox set to refresh on _chg action of the dropdown and it is bringing in the first row but will not find the match. The code is included.

Sub Populate04selldays()
Dim Row As Integer, i As Long, j As Long

Set selling = ThisWorkbook.Sheets("Selling")
TopicCount = Application.WorksheetFunction.CountA(selling.Range("A:A"))
For Row = 1 To TopicCount
If selling.Cells(Row, 1) = cbmonth.Value Then
tb04selldays.Value = selling.Cells(Row, 3).Value

End If
Next Row
CurrentTopic = 1
End Sub

Any thoughts on how to make this match the month then bring in the data in another column?
