Ohm's Law Calculator 1.0

Hello all!
I use Autoit for a while, already made some automation for a TV station's master control room with it. I made a UDF to easily work with PAL timecode and time with milliseconds, convert, add or subtract them. Feel free to use it if you want something like this

hi everyone!
I need some help with my rpn calculator.
I first translated it from vbscript to autoitscript and that's when i stumbled on problem one:
(46) : ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.:
$Stack[ubound($Stack)] = $Item
^ ERROR
After that (and i know this from testing it as a vbscript) it can't work with negative numbers:
"1 - - 2" to Reverse Polish notation = "1 - 2 -" gives me the build in error...
 
Can you guy's help me with my code pleas?

Reverse Polish Notation (RPN) is a math notation in which each operator follows its two operands. I own an HP 48G calculator which uses RPN, and when I tried to use the windows calculator I had so much trouble that I wrote my own calculator. Basically, it has a stack of numbers; any time an operator is pressed, that operation is carried out immediately on the two items on the bottom of the stack, or the stack and the input if there is anything in the input. This method reduces the requirements for parenthesis and makes calculating equations/functions relatively easy: instead of
(sqrt(5+8))/(8*9)
you would enter
5 ENTER 8 + SQRT 8 ENTER 9 * /

Practical implications

Suggestions/advice/criticisms are greatly appreciated!

Here's a graphing calculator I've been making,
It can graph most functions and solve basic derivatives and integrals

I haven't gotten around to making functions for solving indefinite integrals yet,
and i know that my derivative functions don't work for all types of functions.

please post any feedback,
