Employees while submitting the time card are trying to understand the mistake they are making but there is no error message being displayed for them to correct what is wrong.

We've been trying this multiple times. In very rare cases message gets displayed when you do double right click on the cell. But most of the times it doesnt, no matter where or how you click on the cell on the time card.
