If anyone is interested, I found a way to automatically adjust a row height based on merged cells text. Here's how I did it...

In a cell unmerged and on the same row as the merged cells, enter the formula = merged cells and set the formula cell to the same column width as the combined merged cells. For example: Merged cells are B2:D2, formula in F2 is "=B2". Then set column F width to match merged cells. So if the merged cells combined column width is 30, set column F width 30.

Then in the worksheet VBA, use this code. This will automatically adjust the row height after the text in cell B2 is entered.

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Row = 2 Then
ActiveSheet.Rows(2).AutoFit
End If
End Sub

Happy VBAing.
