These are two Cell Ranges A10:B22 on both Worksheets that are Date Formatted.
So if the same dates are inputted in the worksheet an alert or error will
show so that this can not be used.

Thanks

Are these 2 different cells specific cells? Or are they from cell ranges? You
might be able to use data validation, but would need a better idea of what
cells (or ranges), you are working with.
