having trouble with bitwise or

I made a procedure that scans for all blocks in a certain range around a player using global variables and in order to do this I used bitwise or but now the build console is saying that | which I think is bitwise or is a bad operand is there some way to fix this directly or achieve my desired result without using bitwise or. Here is my workspace for further context. https://drive.google.com/file/d/1hHMq7aT69uCPpq_m_ed8B2s2av1A3VVG/view?usp=sharing
