reset just the current table instance

Good day,

I asked a question years ago about resetting just the current table instance and I received a reply from Radzar which worked.  Now, it's not working and I can't seem to understand why.  Below was the correct answer to my question.  I recently created another form and used the exact same script, now when I click the button it first clears the information in the first (2) rows of my table.  When I click it again, it clears the information in the other rows.  Any help is appreciated.

form1.howobtainedsubform.cardssubform.CARDS.Table1.Row11.adddeletesubform.erase::click - (JavaScript, client)
if (xfa.host.messageBox("Are you sure you want to erase all entries?", "Reset the form", 2,2) === 4){
xfa.host.messageBox("All entries have been removed");
xfa.host.resetData(CARDS.resolveNode("Table1[" + this.parent.parent.parent.index + "]").somExpression);
}
else {
xfa.host.messageBox("No entries have been removed");
}
