Hi guys. I'm sorry if this is a basic question but I'm stuck. I have a function that I need to keep very general, since it's attached to a switch menu where I test three different structural elements from three differents POV (frontal, crest, back) using another switch menu. The problem is that I need to detect colors, but colors change in type AND also in quantity. Being the max number 3, I have a problem in the crest where I just have one color. The best way would be to 'mute' the variables of the other 2 colors but how do I do it? If I put  the program crashes. Basically sometimes I don't need to use all the variables and I need them not to interfer with the rest of the code.
