Query With A Table Name That Has A Space...

I have a table name in SQL Server 2000 that has a space in it
ex: aim international

I had trouble just in the query analyzer with this..I had to place the
name in brackets [] for it to work. But now I'm in Visual Studio .Net
2003 and it gives me another problem. I get the table name from a drop
down list selection and send it to a query string. But is gives me this
error:
***************
Line 1: Incorrect syntax near 'AIM international'.
Exception Details: System.Data.SqlClient.SqlException: Line 1:
Incorrect syntax near 'AIM international'.
******************
Here is the string:
****************
Dim sqlStr As String = "SELECT DISTINCT Last_Name FROM '" & PubName &
"' WHERE PostalCode ='" & postalcode & "' And Title='" & title & "'
ORDER BY Last_Name "
**********************

And the variable PubName is the string AIM international .
I tried placing it in brackets like in the query analyzer :
****************
Dim sqlStr As String = "SELECT DISTINCT Last_Name FROM ['" & PubName &
"'] WHERE PostalCode ='" & postalcode & "' And Title='" & title & "'
ORDER BY Last_Name "
*******************

and I get this:
*******************
Invalid object name ''AIIM international''.
Exception Details: System.Data.SqlClient.SqlException: Invalid object
name ''AIIM international''.
*******************

Any idea what I have to do for it to work ??? Can I use table names
with spaces or it's just not a good idea???
Thanks for the help guys!!
