Additional Images - Changing the Images per Row

Hi All,
It seems like this as come up before , but I can't seem to find the post on it. 
I would like change the number of additional images that appear on each row under the main image on the product detail page.  Right now, it is 3, but I want 4.  I have found code in the ViewPrdCode.asp file around row 1378 that says:

'// When the product has additional images, this variable defines how many thumbnails are shown per row, below the main product image     if pcv_intProdImage_Columns="" then         pcv_intProdImage_Columns = 3     end if

However, when I change this to 4, it does nothing.  I have expanded the width in the CSS file, so there is room to show 4 images.

Has anyone else tackled this issue?
Thanks
Curt

I am using V4.1sp3, and I don't see any reference to the additional images in any file except the viewPrdCode.asp file.  I have looked in the viewPrdC.asp and the viewprd.asp too.  I found one other instance, in the configurePrdCode.asp file, but that didn't do anything.  Here is an example page.

Aha!  That was the one to change.  Three places, same code, but only this one works!  Sorry, I was blind and didn't see the first time.  Thanks Greg.

Thank you for letting us know. We have updated it.
