Need help modifing / adding to some VBA code

I have a sample file attached. It has working VBA code that's put a "X", in a cell where
a "q" is in the cell directly to the left (in a hidden column).

I would like to be able to have an additional column (working the same way) that
puts a "wingding symbol" in an additional column, the same way (when an "/", is to the left.

I have attached a sample piece of the file / with the current VBA code.

If someone can write / edit the code to work, (if it can be done), it would be greatly
appreciated as I do not fully understand VBA.
I am using excel 2003.

Thanks!!!
