I agree sandeep mewara. Your question is simple. Also it is a simple logic. why you can't write it. you can directly check parenthesis in the expression by using comparison function.

Hello

I would suggest to use a parser.. If the parsing process is successful, the check for parenthesis is then Ok ...

Personally, I often use the parser written Nick Gammon (http://www.gammon.com.au/forum/?id=4649)

It does not work like this here.

Here is what is expected of enquirers:
1. TRY first what you want to do! You may find that it's not that hard.
2. Formulate what was done by you that looks like an issue/not working.

Try them and tell if you face issues.
