Is it possible to make a counter display an equation you have written as a string during gameplay?
For example say you have an edit box containing the string: value( "Counter" )-5
Can a counter display this expression (written as a string) as a value?

Isn't there a difference between the data shown by a counter (strictly numeric) and an edit box (text, special characters, and numbers)?
If so, I doubt one could transfer edit boxes to counters...Although I imagine it is possible to input data in a text box, use it to change an in-game value, then change a counter to display that in-game value. Seems like an extra step, but that might be the way to make it work.

If I'm understanding correctly, he wants to store an expression as a string, and then store the RESULT of that expression as a value.
You can do that using the "Expression Evaluator" extension - although I have a feeling that may only be available for the developer version of MMF2 (not sure on that).

That's exactly what I mean Sketchy. I want to write expressions in-game and the display the result as a value somewhere like a counter. Problem is, an expression isn't a value. And you can't convert it to a value using Val(THE_EXPERSSION) because I don't just want a value, I want the experssion value.
Sketchy, have you had experience with the Expression Evaluator? Is it hard to what I am trying to do? I have MMF2 devolper.

Nope, never tried it.
It seems it doesn't require developer after all - I just hadn't bothered to install it before now. It does look kind of complicated, but at least in includes online help and an example file (in the MMF2/Examples/ folder)...

Evaluating mathematical expressions from a string is really easy with this object. But I'm having trouble defining varibalbes. Feel like having a crack at it?

Nevermind!
I achieved it with the Substring Replace extension.
It searches the string for the substring "a" and then replaces that string with the global value "a" and then that entire string is parsed by the Expression Evaluator extension, returning the correct calculation.
I'll whip up an example later tonight.
