Ahh. So much better. I am glad you took my advice and worked on it :) There are sitll a couple bracket errors. Remember it is just simple addition and subtraction

say...{ are positive and } are negative. In the end it must equal 0. Where you place the brackets can also change your script just like in an equation. (4+4)5 is compeltely different than 4+45

So suppose we opened 3 { now we need to close them. soo...

3 + -3 = 0
{ + } = 0
{ { { } } }

Hopefully that makes some sense o.O
