How to Check String in top row of active column

I am a new to VBA (fun!) and am trying to write code that determines if the top cell (on row 5) of  the active column  contains a specific string.  e.g. "Sun".  I understand how to use the intstr, but cannot figure out how to change the range/cell reference in the bracket to reflect a different column.  Thanks for any advice at all!!!

 If InStr(1, [b5], "Sun", vbTextCompare) > 0 Then
MsgBox "It is Sunday."
MsgBox "It is not Sunday"
End If

I do not use VBA but I know you can use COLUMN() to retrieve the current column.

To test Row 5 for the "active column":

If InStr(1, Cells(5, ActiveCell.Column), "Sun", vbTextCompare) > 0 Then

Open in new window

BTW, nice going on remembering the vbTextCompare.  Most people forget that VBA's default for text comparisons is case-sensitive :)
