Dear guys!

You helped me a lot before, and now I have a new question, for whose know the anwer. I want to make a script, which helps to calculate (and I found a lot of script which can calculate) BUT (!) Is there anyway to make one, which gets the information from another partner (in chat window) and gives the solution at the same chat window?

For example: Peter says: - 5+5*2=?
     (My script)  I say: The solution is 20.

Thanks for the answers before!
