Help with adding a new combo box in a tab database

[Alvarogue]

I need some help to make a combo box. For some reason when I try to make the combo box and grab the information, it erases all the information on the fields of the other boxes and doesn't work!

anyone willing to give me a hand with that?

it shouldnt unless youve advanced to a new record.
are all fields bound to the query/table?
is there any event code in the combo?
is the form set to dataentry?

There is an event procedure in the other combo boxes in order to filter the information.
They are all bond to the table, but its arranged weird so IDK if its a problem of the other comboboxes or an common error for misstyping the Dlookup function.

What do you mean by dataentry?
