Thanks for your help! it worked! however there's a message showing everytime the user creates a table like

"you are not logged on as the databae owner or system administrator. You might not able to save the changes to tables that you dont own"

After i click ok, i can still enter the fields/columns for the table then everytime i click on the save icon another warning message appears like

"warnings were encountered during the pre-save validation process and might result in a failure during save. Do you want to continue attempting save?

After i clicked "yes"; the table did saved, however will there be any errors in the tables due to the warning statements i received earlier? why are these statement showing?

Thanks,

Aileen
