Error "Invalid entries found. Please correct and submit again." Lookup Fields?

Error "Invalid entries found. Please correct and submit again." Lookup Fields?

Hi,

Everyone I have just completed a database and I am getting the error " Invalid entries found. Please correct and submit again." I am guessing that it might be some kind of problem with the Lookup Fields and the dynamic update I have on dropdown list. Anyone has any idea on how to solve this?

Please let me know.

Regards,

Leandro
