Probably a simple problem, but thus far I've not been able to solve it.
I have a main form with a sub form; the subform is linked to the main form by an automaticly generated number as the subforms PK.
I can view and edit data perfectly, however when I try and add a new record to the sub form I get a message telling me that the field CAD_ID (subforms pk) is read only. Thus is will add a record to the sub form, but not link it back to the main form.
I'm wondering if the auto generated number is causing a problem somehow?
I'd be most gratefll for any ideas!
