Stored Procedure Syntax - Value Not Returned

I have the following stored procedure. The good thing is I finally got the syntax to the point where it doesn't blow up, but I was under the impression the "print" statement would print my result. In this case all I get is the statement ' 1 Row Affected ' which by the way is not the answer I was expecting.

Here's the code:
'
CREATE PROCEDURE createevents
AS

declare @myvariable varchar(700)

declare @myvar varchar(700)

begin
Select @myvariable = d.id
from table1 d, table2 dc where d.class = dc.class

If @myvariable > 0
begin
Select @myvar =dp. class
from table3 dp, table2 dc
where dp.class = dc.class

If @myvariable >= 1
begin
print @myvariable + (',') + @myvar
end
end

else
begin
print @myvariable + ('is empty')
end
end

'
Thanks in advance for any help.
