Hi Magicloud,
restrict (t!T.done .. constant False) should dot it
but your t!T.done confuses me, is the the T.xxx due to an import?
also the line 49 does not seem to be right. Would you mind to post your
table and column definitions?

I changed it, some other problem occured.
1. How to compare a BoolT column to a True? t!c .. True could not work.
2. What shoud I use after !? Like table!col, recordset!col, what is col?
Thanks.

Hi,
I am learning it following the very few documents on its site. Well,
