complicated image swap, link call

[opperman]

I'm having difficulties getting this to work. The desired action:

Numbered navigation system (1,2,3,4, . . .). OnClick number, an image swaps (this works), when the user clicks on "View Larger," the page knows to pop-up the right page. Each image has a larger view html page that matches. I tried creating a var for the images, then assigning the variable value with the OnClick, then using a if and else if with the "View Larger" link to pop up the windows. Not working.

www.tunnelstudio.biz/test/bellacor/bellacor_test.html has the right action (if the user clicks on "old", but doesn't pop up the right window.

www.tunnelstudio.biz/test/bellacor/bellacor_test3.html is the page with the following JavaScript. I'm am indeed a newbie and appreciate all advice.
Best,
Michael
