Truncation errors using Excel Connection Manager - VS2008

Hi

I am in the process of importing an Excel Spreadsheet using the natively connection manager in SSIS 2008.  There is one column however that is causing me grief.

SSIS has natively chosen the problematic column to be a DT_WSTR(255).  So I have gone into the Excel connection manager's Advanced Editor and altered it to be a DT_WSTR(1000) (see image 1 attached).

I am still getting truncation issues though, as per image 2 attached.  Any ideas as to why this is?

Thanks in advance
