Report returning partial field

Hi,

I am using Crystal Reports 8.0.1.0 connected to a SQL database via ODBC.  Crystal is truncating some fields and I am not sure why.  It truncates in record selection, printing, and grouping. 

For example, we have a table listing vehicles and model year (number field) truncates in all our reports.  Model years with 1, 2, or 3 digits will return, group, select, and print correctly.  Model years with 4 digits return, print, group, and can be selected on only the first digit.  See below for illustration:

Vehicle Main Table sample

A single table report looking only at Vehicle Main with no selection criteria will return this:

If grouped by model year, the output is:

6

     AAA111

95

     BBB222

199

     CCC333

1

     FFF666

2

     DDD444

     EEE555

Anyone know how to correct this?

Thanks!
