Select statement comparing a uniqueidentifier field

Hi,

I'm attempting to compare information in a uniqueidentifier field using a
select statement and am having fits trying to get it to work.

Here's a sample of my SQL statement.

SELECT Organization.TreatAsTypeOf_ENUM, Organization.OrganizationID,
Organization.Organization, Organization.Email, Organization.URL,
Organization.Phone1, Organization.Phone2, Organization.ExternalAccountID,
Organization.CustomerTypeGUID_FK, Organization.BranchGUID_FK, Address.*,
CustomerType.* , Branch.BranchGUID, Branch.ParentBranchGUID

FROM (Organization LEFT JOIN Address ON Organization.BillToAddressGUID_FK =
Address.AddressGUID)
INNER JOIN CustomerType ON (Organization.BranchGUID_FK =
CustomerType.BranchGUID_FK) AND (Organization.CustomerTypeGUID_FK =
CustomerType.CustomerTypeGUID)

INNER JOIN Branch ON (Organization.BranchGUID_FK = Branch.BranchGUID)

WHERE Branch.ParentBranchGUID = '{65F02099-8E4C-4483-91B8-90AEF2838E76}' AND
CustomerTypeID = 'Home Owner ' ORDER BY Organization.OrganizationID

The part I'm having issue with is the WHERE statement. When I try to open
the recordset I get this error:
Syntax error converting from a character string to uniqueidentifier.

If I compare a uniqueidentifier to another one it works but if I try to save
the information and use it, I can't get it to work.

I'm doing this in VB and would LOVE some assistance. This is making me
crazy and I can't find any information on the web.

Thanks

Sue
