Debugger Error:Invalid scope kind

Yes, but you wont be able to run it ;-)

Ok the code searches through 3 lists to see if the objects are of the same colour.
On the first iteration it gets to the PlaySound sPop statement, assigned the links again then returns to the first IF statement within the While loop and the error pops up where I've put the asterix
