Variables giving me a problem... [resolved]

I want to be able to calculate and store a percent..  Since the default variables don't hold decimals and can only perform one mathematical operation at a time I figured I would try to use RGSS to perform my calculations and store the resulting percent back into one of the default variables..  This was the line I used to try and store the value:

$game_variables[17]=($game_variables[15]/$game_variables[16])*100

When I do this though I get the following error once the game reaches that line:

nil can't be forced into Fixnum

Anyone know what mistake I made?..

edit: added resolved tag

I take it you are trying to run that with the Event Script command.

It's too long - the interpreter interprets it in the wrong way for your purposes.

Try this:

Code: [Select]

a = $game_variables[15]
b = $game_variables[16]

$game_variables[17]=(a / b)*100

On the other hand, you could also avoid RGSS totally by just multiplying by 100 before dividing in the events like this:

@>Control Variables: [17] = Variable [15]
@>Control Variables: [17] *= 100
@>Control Variables: [17] /= Variable [16]

Ah yes, I don't know why I didn't think of that.  That helps a lot, thanks..
