Conditional formatting with icon sets

Hi,

I have attached a Yearly Goals template that I have put in place to rate the players that I coach with regards to their progress made/targtes hit.

I wanted to use the icon sets available in excel to give the worksheet a professional look. I could not work out how to use the icon set where text was inserted so I used the following formula -

=IF(H11="R",3,IF(H11="A",2,IF(H11="G",1,"")))

and had the relevant icon appear in "H12", I then formatted the "H11" cell white font so it look liked when R,A or G was inserted the said icon would appear.

The problem I keep running into is that because I have made the text column narrow and white font (as I really wanted it so it looks like just an icon appears) coaches that are filling the template in will automatically delete the icon if they have made an errror when inputting their rating!! This then deletes the formula, which in turn means the conditional formatting is not applied.

To cut my above ramblings short lol!! I was hoping that there was anyway I could use text for icon sets to eliminate the need for using a formula!!

Thank you
