I am trying to learn javascript

**marcorow** · 06-15-2012, 07:22 PM

I copied a javascript to change pictures onload on a page. I have this script running successfully in many other pages. This time I am trying to use the same script twice in the same page (with different names) but I am not able to figure out what else should I change to make it work. I can get it to work in one place at the time. I believe I need to rename some of the variables but I am not sure which one.
can anybody help me?
here the 2 scripts:
1
pics.js
