SQL View With Text Field

When creating a View, I am able to link the tables togethor and pull the data that I am looking for without a problem. However, when I add a field that is a 'Text' field, I get the following error:

....Column 'dbo.commpay.fdescript' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

If I add it to the GROUP BY clause, then I get the following error:

....The text, ntext and image data types cannot be compared or sorted, except when using IS NULL or LIKE operator.

This particular field is contains the description of the parts in our inventory table.


VIEW Statement:

SELECT dbo.armast.fcinvoice AS Invoice, dbo.commpay.fnCalcComm AS Commission, dbo.commpay.fnrate AS CommRate, dbo.armast.fbcompany AS Company, dbo.commpay.fdarpost AS InvDate, dbo.commpay.fpartno AS PartNum, dbo.commpay.fnamount AS Price, dbo.commpay.fsalespn AS RepID, dbo.commpay.fmdescript AS Description
FROM dbo.armast INNER JOIN dbo.commpay ON dbo.armast.fcinvoice = dbo.commpay.fcarinv INNER JOIN dbo.slspns ON dbo.commpay.fsalespn = dbo.slspns.fsalespn
GROUP BY dbo.armast.fcinvoice, dbo.commpay.fnCalcComm, dbo.commpay.fnrate, dbo.armast.fbcompany, dbo.commpay.fdarpost, dbo.commpay.fpartno, dbo.commpay.fnamount, dbo.commpay.fsalespn, dbo.commpay.fmdescript

Any assistance or guidance would be appreciated!
