I have a form in which users will create a formula inside a textbox.
I need to test the formula and see that it works before I can allow the user to continue.
I am having trouble trying to evaluate the expression. It could be a complex formula or something as simple as 1+(100*2)
The only way I can see to do is is to parse the string character by character which I was hoping not to have to do. Anyone have any ideas ?
