q1: every form-field-spec in the form constraints is a Tcl list element. therefore use
Form:
@mc@
Constraints:
{mc:select,required,options={yes 1} {no 0}}
q2: There is a but in some tdom versions that convert the given text to
<form>
<select name="standards">
<option value="1" selected="selected"></option>1
<option value="2"></option>2
<option value="3"></option>3
</select>
</form>
which is not displayed. an upgrade of tdom from cvs should help.
q3: unknown variable 'myvar'
The message says, that there are form entries in your database that have this variable not defined. This is most likely due to the fact that you have changed to form after some instances got some values. Most likely, you can deleted some earlier form instances to get rid of the warning message.
