VBA Conditional Formatting Runtime Error '5' Invalid Procedure Call

Thank you for looking at my question,

I want to format a range of cells on a worksheet using VBA (Excel 2013):

    .Range("A3:U" & lngBOMRows).Select
    With Columns("A:U").FormatConditions.Add(Type:=xlExpression, Formula1:="=IF(Q1>U1)")
     .Interior.PatternColorIndex = xlAutomatic
     .Interior.Color = 15773696
     .StopIfTrue = True
    End With

For the range A3: last cell in U, if the value in Q is greater than U

but I get a runtime error and invalid procedure call message.

This also happened when I tried to set the font of a range of cells.

I looked in the References, there aren't any there flagged as missing, presumably there is one that hasn't been ticked but I don't know which it is can you help?

try change formula: =IF(Q1>U1) to =Q1>U1 and try:

.Range("A3:U" & lngBOMRows).Select
    With Columns("A:U").FormatConditions.Add(Type:=xlExpression, Formula1:="=Q1>U1")
     .Interior.PatternColorIndex = xlAutomatic
     .Interior.Color = 15773696
     .StopIfTrue = True
    End With
