Multiplier Skript Help

[SnaderMC]

No errors in the Skript. Why doesn't this work?

set {money.%player%} to ({multiplier.%player%} * {money.%player%})

 

[SnaderMC]

{money.%player%} has to be greater than 0 to start off, and what does it output?

Heres the skript, only multiplier don't work, the rest works as it should.

loop 2304 times:
    loop all items in player's inventory:

There's so many things wrong on that code, anyways what's the value of {money.%player%} and have you tried

add  {money.%player%} * {multiplier.%player%} to player's balance

My code works at it should, and simply my question is "how to multiply two variables"

 

[SnaderMC]

Oh great, one of those who won't accept criticism

Your code IS wrong.

The answer to your question is simple my man!

set {RESULT} to {VAR::1} * {VAR::2}

Off-topic: Let's say 30 players execute the command, imagine iterating 2304 times over ALL ITEMS IN PLAYER'S INVENTORY

Already tried it, didn't work for me.
And I would be glad if you have something I could do better in my skript.

 

[SnaderMC]

I've told you one thing you could do on your Skript, anyways what's your Skript version?

Don't know, but when i try "/sk update check" it says "You're currently running the latest stable version of Skript."
