IDIOT NEEDS HELP comparing a variable against a list

I have a variable called @.ORComm which has been selected using a cursor from each line on an order.

DECLARE TC2 CURSOR FOR
SELECT [Commodity],[Total] FROM [CSITSS].[dbo].[Ordrate] WHERE [OrderNumber]= @.OrdNum AND [Companydiv] = 'GLPC-TRANS'
OPEN TC2
FETCH NEXT FROM TC2 INTO @.ORComm, @.ORTotal

I need to compare the resulting @.ORComm against a list of valid commodity types selectable by

SELECT [CommodityClass] FROM [CSITSS].[dbo].[Comclass] WHERE [CompanyDiv] = 'GLPC-TRANS' AND [DELETED] = 0

What's the easiest way to do this?SELECT [CommodityClass] FROM [CSITSS].[dbo].[Comclass] WHERE [CompanyDiv] = 'GLPC-TRANS' AND [DELETED] = 0 and CommodityClass=@.ORComm

??|||I feel stupid I didn't think of that. I was thinking of storing the selected values in an array but that is much simpler.
