It would be *so* much simpler if you could take the time and effort to
construct a minimal reproducing example.  One that people could simply
run, without having to jump through *hoops*, to check your results.

unicorn:~$ bash-5.1
unicorn:~$ takes=
unicorn:~$ kwsi=42
unicorn:~$ (( takes && kwsi += takes ))
bash-5.1: ((: takes && kwsi += takes : attempted assignment to non-variable 
(error token is "+= takes ")

There.  Was that TRULY so difficult that you could not do it yourself?
