Multiple Dynamic Tables on the same Form

Still getting used to working with Adobe LiveCycle.  I am building a form that I want multiple dynamic tables included.  I added the first one and got it working thanks to some postings on this site.  I then went to create another the same way and this one doesn't want to add new rows like the previous one.  I copied and pasted the code in the "Add buttons" and made sure the same properties were set for each table and sub for, but no luck.  here's a look at the structure:

The code on the buttons:

var rowNum = this.parent.index + 1;

this.parent.parent.instanceManager.insertInstance(rowNum);

Any ideas, or need more information?
