Why Wont Value Turns False in scripts and manual check but does in output?

I have this part of my amazing code--->

and this is in a normal script in workspace... My problem is before i test the game, i set the value to true, i check and its true while playing game, and when the script fires. sure enough- the output says true, but then the can=false fires then the output fires and says "false", which means it just worked, but i manually check the value that is in player's backpack and i see its still true, then i press Q again (whole thing is executed by clicking button Q) and this whole thing fires like it was true, but the output says false, but manually checked and it said false, and s=the script acts like its false, i dont get it, please help! thanks

Cover: Scripts acts like can = TRUE Manual Check Shows can = TRUE Output tells me can = FALSE

plz halp fast!
