I'm trying to create a conditional format on about 150 rows in my
spreadsheet

Range("A4:L4").Select
Range("A5:L5").Select
Range("A6:L6").Select

Up to

Range("A150:L150").Select

Using these three condition

Selection.FormatConditions.Add Type:=xlExpression, Formula1:= _
"=$M$4=""xxxxx"""
Selection.FormatConditions(1).Interior.ColorIndex = 4
Selection.FormatConditions.Add Type:=xlExpression, Formula1:= _
"=$I$4=""yyyyy"""
Selection.FormatConditions(2).Interior.ColorIndex = 38
Selection.FormatConditions.Add Type:=xlExpression, Formula1:= _
"=$I$4=""zzzzzzzz"""
Selection.FormatConditions(3).Interior.ColorIndex = 40

(In the condition I would use the variable count to go to next row)

I tried creating a loop with a counter but I can't get my variable to
worth in the ranges.

Any help would be greatly appreciated.
