unable to import from excel 2007 on sql server with nvarchar data type

My column has a data type of nvarchar(255) in sql server 2005 so I can import from excel 2007. I am using ssis 2005 to import.

Excel Source to OLE DB Destination and getting the following error.

[OLE DB Destination [4348]] Error: SSIS Error Code DTS_E_OLEDBERROR. 
 An OLE DB error has occurred. Error code: 0x80040E21. An OLE DB record is available.  
Source: "Microsoft SQL Native Client"  Hresult: 0x80040E21 
 Description: "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, 
if available. No work was done.". 

Any ideas. 

Thanks for help
