Problem inserting a row containing GUIDs - Mailing list pgsql-novice

I am currently receiving an error message each time I try to insert a row.  The row contains several GUID values, and when I try to do the insert I get an error like ‘Syntax error at or near ‘a45’.  I’ve tried to enclose the GUIDs in quotes but I still get the error. 

Any help would be appreciated.

Here is a little more info:

OS – Windows XP Pro SP2

Postgresql v8.0.3

Provider – NPGSQL
