Problem importing Access table into SQL Server

I am trying to import an Access table into SQL Server using the SQL Server Import and Export Wizard.
I created the SQL Server table using the same field names that are in the access table.
After selecting the Source and Destination tables in the wizard I get the message "Found 7 unknown column type conversion(s)".  The seven fields are all text fields in access that I am mapping to nvarchar fields in SQL server.   There are other text fields that map successfully.  Can  anyone tell me what my problem might be?

You don't need to create a table before. The Import/Export wizard will do that for you and give suggestions for the data types. Do that to see what the wizard suggests for those 7 columns. You can change the data types during the process.

Are the suspect fields identified by SQL Server?

Also make sure that none of your Access fields are "Access Only" datatypes:
ex: Lookup Fields, multivalued fields, or even fields formatted as "Rich Text" (HTML)

when I try creating the SQL table using the wizard it shows a data type of -1 for these fields. It lets me change the type to nvarchar with a size of max.  It does not allow me to change the size to the appropriate length.
