Evaluate in custom function

[normanicus]

Is it true that the evaluate function does not work inside a custom function?

No that is not true.

David is right, but what you have to remember is that it should be used with restraint, multiple iterations are going to stress the processor quite a bit.

Q. How does the Evaluate() function perform compared to other functions…if is slower, why?

A. Have to parse it…can be more expensive, but take some parsing time…great to be able to use it but it may be more expensive. (CC)

Thanks for the quick answer. In the meantime I discovered I can achieve what I want with GetField(). I must have been doing something wrong in my efforts with Evaluate.

Could it be this:

Evaluate(TextField) returns 4 when TextField contains 2 + 2.

Evaluate("textfield") returns 2 + 2 when textfield contains 2 + 2.
