SQL Printing Problem (Stored Procedure Dynamic Programming)

Ive put this into the query Analyzer just to see that the str variables (strCMDAND & strCMDOR) are being built properly
but near the end before the

declare @strPropID varchar(35)

--Put the entire string together so that it can be executed. 1=1 is for the extra AND that will be at the end of the next condition since we dont know when it will stop adding conditions

Print('Hello')
Print(@strCMDAND)
GO

This print statement will not work just a blank blank comes out but the Hello does appear.. its very strange the variable will print before the set statement but not after.. Some Help would be appreciated
The print statement will be changed to EXEC in the SP

I figured it out already.. I forgot to initialize @strCMDOR....
