Hi. Prior to a macro executing, I would like to have the code check a
certain condition. If Cell A1 is not blank, then B1 is a required field.
So conceptually, look at the entire Sheet1, scan column A. For each cell in
column A, if a cell is populated, then cell B should be too. If not, Msg
Box (ideally detailing what cell triggered the Msg Box) and end the sub.

I am thinking this is a separate Sub that will run prior to the main sub.
It does not have to check the Sheet dynamically. I just can't have the Main
Sub execute with missing info. Can anyone help? Thank you!

Use code like the following:

Dim Rng As Range
For Each Rng In ActiveSheet.UsedRange.Columns(1).Cells
If Rng.Value < "" Then
If Rng(1, 2).Value = "" Then
MsgBox "Blank cell in " & Rng(1, 2).Address
Exit Sub
End If
End If
Next Rng
