javascript error on demo with current mysql table

[DiegoJArg]

Hi.
I need to make a table easily editable for highlevel users.
demo and demo table works fine as it comes.
If I change database and rable to formtools -> ft_form_1
I get this javascript error.
Sorry, but it lacks of details to know what to send to you
