Question : Yes/No fields in Access 2007

I've never had this happen but I just added a bunch of fields to a table and now and trying to add them to the corresponding form.  They are designated as Yes/No in the table but are inserted in the form as regular number fields instead of check boxes. Also, if I re-insert old fields that were shown as check boxes, they show up as number fields.   I tried inserting them into a blank form and the same thing happened.  Any ideas?  Thanks!!

Answer : Yes/No fields in Access 2007

you have to change that to check boxes if you want to see them as checkboxes in the form. here is a quick and dirty way
add a new Yes/No field. save table, view if the field contains check boxes

run an update query to pass the -1 and 0 values to the new field
delete the -1 and 0 showing field. rename the new field
