How to change an input type (parameter - variable) based on another one? (Wildcards)

I searched the files for “CompactNodeTitle” and didn’t find anything relevant that would remove the background “icon”.

And believe me, going through the archives I found the “SetParam” thing by accident (referenced in one place, but I didn’t get to the location you mentioned. At least I think so). lol

I would like to add that I was able to remove the “error” when trying to remove one of the input connections. I added an extra code (which I already knew) and it simply resolved like a charm (I don’t know why, what matters is that it worked, hahahahaha). I felt like a genius at that moment.

Thank you in advance for your help. I won’t forget what I learned here today with you. I also believe that others (newbies like me) will get full benefit from this topic.

See you!!!
