CHECK BOXES

[Rich_Lovina]

Why when I drag my fields into form design, would only one field automatically come out as a checkbox, whilst other yes/no defined fields not? then when I try to change by right-click, the checkbox options are 'greyed out'. Any help greatly appreciated.

Tks, I tried that and also ensured Lookup tab selected for checkbox, but still can't get it. Strange too is fact that only checkbox created correctly is from an inner joined table's field. I suspect Access corrupted but ran repair/maintenance also. Any other ideas?
