Unfortunately, I'm not able to debug the code like that.
I tried to look for some indications of problems with FireBug, but do not get any errors.
I was able to find the code part where you indicated errors, but have no idea how I can influence these, as I did not modify any code there..
The rest of the site seems to work, though, I'm sure it could have some hidden problems.
Would you have any suggestions on how I could proceed?
Here's almost the same web site (the main one) without your code.http://artisansjewelry.ca
I'm not even sure if the same errors appear there, I guess they do.
