I have the following code called by the Workbook_SheetCalculate event. It
works, however it seems to have a mind of it's own. When I check the
conditonal format of Cell G2 it reads =AND($H3="",$G3<=TODAY()). It should
read H2 & G2. I don't understadn what is causing this, however I could
adjust my code to offset by one. But then othertimes the numbers are way
off, on some sheets I just get a !REF error in the formula.

What am I doing wrong that Excel won't start at G2 and autofill down
incrementing as needed

For Each Sh In ThisWorkbook.Worksheets
shLast = LastRow(Sh)
With Sh.Range("G2:G" & shLast)
.FormatConditions.Delete
.FormatConditions.Add Type:=xlExpression,
Formula1:="=AND($H2="""",$G2<=TODAY())"
.FormatConditions(1).Font.Bold = True
.FormatConditions(1).Font.ColorIndex = 3
End With
Next

Function LastRow(Sh As Worksheet)

LastRow = Sh.Cells.Find(What:="*", _
After:=Sh.Range("A1"), _
lookat:=xlPart, _
LookIn:=xlFormulas, _
searchorder:=xlByRows, _
searchdirection:=xlPrevious, _
MatchCase:=False).Row

End Function
