jQuery in iMacros

Hi
I am trying to code a macro which will do the following

1. Open a csv file
2. Goto url in the csv file
3. Run 3 javascript snippets to go to bottom of page and 1 jQuery code to count number of divs
4. Create csv file with the number from Step 3
5. Loop


I can't get the jQuery to work. It shows $ is not defined.
Can some one tell me how to add jQuery to work?
I googled it but the DOM manipulation to add script or the HttpRequest are not working for me.

Regards
