Morning,
I'm not sure whether either of the previous answers actually capture the full requirement. I've understood the question to be that under each colum CF to CX you want to place as many X's (upto 4) as are represented by the numerals 0 to 9 in columns F to I. My suggestion is to enter the expression below in cell CF98 and copy it down to CX101, the IF statement will prevent it showing anything when the column heading is blank, such as in column CG.
=IF(CF$76<>"",REPT("X",COUNTIF($F98:$I98,CF$76)),"")
Hope this helps.
