Can't Add Records to a Table

[Brennan]

Hello:

I have an 2003 Access adp and there is one table which opens but doesn't
allow me to enter any data into the the table. I first noticed the problem
with a form bound to the table. I went directly to the table and any options
for entering or deleting data are grayed out. I can view existing data
without a problem. All my other tables are fine. My backend database is SQL
2000

Any help would be appreciated
Thanks
