Thanks Paul,
My button has focus, then I add the code: Table1.Row1.instanceManager.addInstance(1); in the JavaScript language bar for the click event, but still no joy when I try it in Preview.
Once I add it the code also appears when FormCalc is selected and "Click" has an asterix appended to it: "Click*"
Asiye,
I have forwarded you a copy.
Thanks to you both,
Smitty
