Conflicting multiple slideshows on same page

[ComedyFarm]

I have copied and pasted Photoslider II onto my index page. It works fine but when I paste more than one everything gets screwed up. People suggest duplicate variables but nothing I do straightens the problems out. I am pasting the code below, hoping someone can tell me how specifically I need to make the changes so three of the same slideshows work on same page. I am by trade a comedy writer and definately not a programmer. (That's probably obvious.) Thanks for your help. I am also curious if it's possible to tweek the code so I can click on a thumbnail in the slideshow and a larger version of same pic appears in a separate pop up window. ComedyFarm
