Question : Unable to ascend/descend sort on column in table in Access

We have a simple Table with a mix of text, date/time fields.  

The table is INNER JOIN with another table called Category.  The Category table has 10 rows.  The join is on the Category field from Category table to the Category field on Contacts table.

When we do a open of the Contact table, go to the Category column, right-click and do Sort Ascend or Descend we get this message:

Type mismatch in expression

Looking for ideas on how to resolve this problem before going further with this database.

Answer : Unable to ascend/descend sort on column in table in Access

No, you are suppose to sort without any problem.

In my first comments I suggested to check if you field was calculated or based in a user function. You stated that not.

After all coments I would suggest  you to check if you do not have any other field in the table wich is calculated or based in a user function and verify if it is not returning any null value or if you are not entering any value that is generating error in the user function (for this other field)
