i want to use a array to store some data. All data are in 'date' type. The data will be used to be a RowSoure in combo box. I can do it in form designer without any error. But when I run the form, an error comes out that the data type is mismatched in the combo box. But, although I have an error, the form and combo box still can work.

Do you know what's wrong?

Any idea is welcome.
