I have tried to delete it and reimport it but the table I have setup in Access still can't pick up on it.
I am finding your statements a bit confusing. I cannot tell if you have imported the table or linked it.
If you deleted the table in Access, there would be no table to pick it up.
Linked tables and imported tables are two very distinctly different things in Access.
If you import the data into a table in Access, the data physically resides in an Access table that is not connected to anything on the outside. So any changes to the original Excel file wuld NOT affect the Access table, and any change to the Access table would NOT affect the original Excel file.
If you link the Excel file into Access, the data does NOT physically reside in Access, but there is a link in your table objects out to the Excel file. So any changes in one affects the other, though changes to table structure probably will not be reflected unless you refresh the link afterwards. In the Access table section, the icon looks like an arrow pointing to an Excel icon.
So, which one do you have?
If you are not sure, please explain the exact steps you used to import the information originally.
