My company uses another company to serve the ads on our site. These tags they give us are javascript. I am trying to modify the scripts they gave us so I can render keywords inside the script from the meta tags. They say this is possible, but they don't have time to do this. So, me being a complete novice at java, am trying to get it done.

The part of the ad code I need changed is
aj_zone = 'central'; aj_adspot = '154901'; aj_page = '0'; aj_dim ='153018'; aj_ch = ''; aj_ct = ''; aj_kw = '';

I need the meta tag key words to render in the
aj_kw = 'RIGHT-HERE';

If you need more info, just let me know.
