Hello Everyone!

I am workin on an MS access database, using Access 2000 and I get this msg:
"Cannot enter value into blank field on 'one' side
of outer join"
I am tring to insert on 4 tables, using a querry.
On the form I created I have some combos and I allow people to add more items to them while trying to insert a new record on this main form. What I do is I call another form, make them insert the new item and then use the combo.requery comand on the event "On double click" of the main form. But I have several of this combos and sometims I get the error msg I described above.

I noticed that this error has been mentioned on this Forum Before, so if somebody could help me, I would appreciate...

Thanks so much
