you can use use string.replace()

(Just turned my comment into an answer, since I realised that this might actually be what you are asking for)

State modeling for large applications is never simple, so I am a bit unsure on what you mean by "the rest of the project".

However it seems like what you are asking for is how you return values from a functions scope to the calling scope?

When you modify coins in your function like here coins = coins - goalkeeper_price you only modify the local variable coins in the scope of your function. To return that value to the outer scope you can return the new value.

So in the end of your function add this line return coins

Now when you call your function you can set the coins value of the outer scope to the modfied value like this coins = transfer_market (coins, gk, rb, rcb, lcb, lb, rcm, cm, lcm, rw, st, lw)

If you would like to understand more about why it did not work to just modify the local coins variable in your function, you can read a bit about 'call by value' vs 'call by reference'. https://press.rebus.community/programmingfundamentals/chapter/call-by-value-vs-call-by-reference/ (spoiler: Numbers are parsed by value)

The FinalFrame_NewFrame event is raised on a worker thread by your "video device"...thus as you have figured out you need to use Invoke to get access to your pboLive element on the UI thread...but you need to pass across the "bitmap".

I believe you just need this:

I am not sure why do you need a current_state when you can simply toggle is_active on the user:
