Easy issue, but running out of time!

I’m new to AS2 and I have been so frustrated trying to do what I think is easy. I’ve searched and experimented for hours and my brain is sizzling.

I need to have a search box, and when the user types in a term and hits submit, I want it to go to a URL and add “srch=<whatever is typed in the box>” to the URL address. In other words, if you type in “Cattle dog” as your search term, I want the URL to read “http://www.fictionalsite.com/products.aspx?srch=Cattle dog”. This should be so easy.

I have a TextInput box called “search_txt” and a submit button called “submit_txt”.

Can someone please walk me through in baby steps how to do this?

Thanks much!
