This is the most simple and works for one mumber only. You might want to continue loop and change position to get next numbers in string and convert them too.

>>>>Nadya, uaually I do this from another way - build a string the way tyhat it is represented correctly. In my filtering controls I have 2 methods. First is to gather comparison expression from all filtering controls to apply filter. Second - to gather the same, but in user-friendly form. This way you will not require to invent complex string processing, just build it by 2 ways - filtering control returns required string on request ;)

>>>Actually, you're right and I even have these methods already. But neverless, this would be an interesting string problem to solve :)

As you understand, I return each criterion as a string lcCrit, so it might be "between(price, 100,1000000)" for another example.
