Add a pop-up information box to describe a product option

[Reedsburg]

It works great for me with 4.1.5
Not sure if this is the problem you are having but I have had that happen when I had the wrong option name.

{if $v.classtext eq 'Option Name'}

"Option name" needs to be what you use in the "Option Text" field in the product variant
and NOT group name this may be your problem.

Not an expert but hope that helps ya
