I found the pdf by this name 'Adding and removing table rows at runtime'. Works fine for one table. I added Table2 and additional buttons named Add2 and Remove2,edited the JavaScript to reflect the new names. Now I get an error:
Table2.Row2 has no properties
32:XFA:form1[0]:app3[0]:Paragraph[2]:Add2[0]:click
Table and row settings are the same on both tables.
Suggestions??
