Someone help me with a very simple script?

[Heiko]

Because you have an error in your script.

Code: Select all

rTot = rTot + 1 or 0

You are doing arithmetics with an undefined variable. This causes a runtime error.
Use this instead:

Code: Select all

rTot = rTot or 0
rTot = rTot + 1;

You can find out yourself about such errors when using the debug console where runtime errors etc. are reported. -> script editor bug button

If a variable doesn't have a value yet, you can't use it.

ie,

c = a + b out of the blue won't work. you'd first need to do

a,b = 0,0
c = a+b

that'll be ok, because a and b now have values.

Ah, thanks, that makes sense.

Lots of thanks.
