Add more than 7 rows to table?

Hi, I downloaded example from:

http://www.adobe.com/devnet/livecycle/articles/AddingRemovingTableRows.pdf

I changed the code from:
if (nNumRow == 7) {
xfa.host.messageBox("The maximum allowable number of rows is 7. You cannot add any more rows.", "Warning", 3);
}

to:
if (nNumRow == 10) {
xfa.host.messageBox("The maximum allowable number of rows is 7. You cannot add any more rows.", "Warning", 3);
}

But I can't add more than 6 rows.
How can fix this??
