[infinitybht]

Hello, I just installed Aabantcaart days ago, and i wanted to integrate  a popups PHP  script to use it in my store, this script gives me some code  start with <script>... something like that and it says  that i need some at the header and  some above the body tag. since I'm not a pro developer I just  created tow eww blocks and I  had place  the codes in them, then  i  place  the  first block in the  header section of the default  layout  design>layout... but the code  couldn't work. I'm planning to put  Google Adsense codes over there  , so iff this couldn't' work then absence will do also. Please teach me  how to place  code script into abanntcart main pages.

Best regards,
Mohamed Ali
