Unable to choose value from Combo Box

[Sapphire]

Hi,

I cannot choose a value, when I run an ADP form, from a
Combo Box nor can I edit a text field. I checked my
tables in Sql server and all of them have Primary keys.

Some of the primary keys are auto numbers and their
Indentity_Insert property is set to off. I am not sure if
this is the problem.

Could anybody please help me with this? If it is the
Insert_Identity problem, how do I rectify it?

Thanks
Sapphire
