Synchronizing checkbox w/many rows

T

TotallyConfused

Hi I hope someone can help me with this question. I have a main form with a
checkbox. When I check this box off I would like this check to also check
off all the other rows that have the same ID. Can this be done without code.
If not could you give me a simplified version? I am new to code. Thank you
very much for any help.
