Hi,
I have came across this problem too before, and there are a few criteria that might be causing this problem. Now, how did you create the Data Access Page? Did you use the wizard, or did you use the “design view”? The next question only applies to only if you are not able to enter data into SOME of the fields: Observe the fields that you cannot enter data into, what do they have in common that might be keeping you from entering data into them? Their data types? Their controls? If you cannot enter data into ALL of the fields, also check the properties to see what is keeping you from entering data into them, Also keep in mind, if you Promote the fields, you will not be able to enter data into them. The reason why I ask you these questions is so that I know where to start troubleshooting.
Let me know how you are doing.
Regards,
