Hey Guys

Quick question which I'm sure is actually pretty simple but I'm pretty new to this.

I have a piece of code for a program where when a specific checkbox is checked\uncheck ed (In this case "Allyellow" ) it checks\unchecks any checkboxes within a group of 14 with a lightyellow backcolor.

While the piece of code below does this fine it seems to me to be very clunky and it must be possible...
