ok,so debug mode : take a print string and add it on each wire one by one from start to end. Each time it prints hello on overlap the “all before” is ok. then go to where it does not print hello ^^ (i wonder if this not the overlap itself which is wrong, maybe when you overlap, overlap is not detected because or a wrong setting or not a real overlapping)

Thank you, will respond tonight as the RDP session too much of a mission to add and test.
EDIT: I can confirm the Overlap is being fired and going to my call function NumPad1

Herewith screen shot of NumPad1 being called.

I have also attempted to have the Blueprint run when in Map Blue print, it calls NumPad1 but still nothing happens:-

Should I rather be casting Numpad1 to Calc_Output?
