Variance affected object comments in report

I am building a report for gathering details about a variance object.  I am able to gather the affected object part numbers and names, but also need to gather the comments and approved quantities for these items.  I believe this comment data is held with the link class that connects the objects to the variance, but cannot find the correct class to add to the from field on my QB report.  I read some from CS181651 and thought it may be wt.change2.ProblemProduct, but I was not able to get the join links correct, nor do I see any attributes on wt.change2.ProblemProduct that look like the comments.  I'm attachign my current qml.  Any pointers?
