Setting fields within tab panels within list views

I’m attempting to push a formatted date value into a MySQL datetime field.

I’m converting a date object using the following code that should comply with MySQL datetime fields.

var today = new Date(); // New signup date object
var renew = new Date(); // New renewal date object

renew.setMonth(today.getMonth() + 3);

today = utils.dateFormat(today, 'yyyy-MM-dd HH:mm:ss');
renew = utils.dateFormat(renew, 'yyyy-MM-dd HH:mm:ss');

forms.subsMemberships.mag_group_membership_to_mag_subs.subs_signdate = today;
forms.subsMemberships.mag_group_membership_to_mag_subs.subs_renewdate = renew;

The field on the form (which is shown in a tab panel) is a related field. I have tried referencing the field both through elements (it’s named) and by targeting the field itself through the relationship. Nothing seems to work.

My goal is to have a record created in one table that is related to another table with date values. The date values should be pushed into their respective fields of signdate and renewdate. But I keep getting…

Can’t put in a locked scope, name: signupDate, value: 2003-12-15 20:16:34

Please post the complete script..
Because what you do above can’t trigger that error.

“signupDate” is that a element name or something like that?

and to make sure what type is youre field “subs_signdate” of the relation?
