Dear All

I am trying to simply create a VBA script to change the color of the
active cell if the resulting value in that cell is less than 15%. In
that cell there is a simple division formula referring to two other
cells to give a percentage in that cell. I have come to the conclusion
that a Function is better than a Sub but the following VBA script
gives me a 'Value!' error. Any ideas for a rookie, please?

Function EfficiencyRatio()
'
' EfficiencyRatio Macro
' Highlights the cell green if the expense ratio is less than 15%
'
' Keyboard Shortcut: Ctrl+Shift+X
'

Selection.FormatConditions.Add Type:=xlCellValue,
Operator:=xlLess, _
Formula1:="=0.15"

Selection.FormatConditions(Selection.FormatConditi ons.Count).SetFirstPriority
With Selection.FormatConditions(1).Font
.Color = -16752384
.TintAndShade = 0
End With
With Selection.FormatConditions(1).Interior
.PatternColorIndex = xlAutomatic
.Color = 13561798
.TintAndShade = 0
End With
Selection.FormatConditions(1).StopIfTrue = False
End Function
