i am having difficulty adding multiselect fields to mySQL database. i have two..12 items and 32 items resprctively. The validation screen shows them as a single line window with a 'line' (no choice)...when dropped down all the items are there but none selected

The help says the following:

Form Size: This is only useful for select, text or textarea form types. For selects, set this to 0 to be a single select field, set it to a postive number to be a multi select field. For Text fields, set this to the size of the text box, for textarea types, set this to rows,cols to specify the size.

I tried using '1' and i also tried '12' and '32' respectively.
