SQL Trigger selecting another database

I have a trigger to email me when a field changes in one table. I want it to use an email address from a table in another database, how do I do this?

Variables are these:  @Rep varchar(20),  @Sord varchar(20)

@Sord is taken from the table that is being changed in the current database.

This is the line that does not work: -
                  set @Rep = isnull((Select Salesperson from SERVER.dbName.dbo.Table
                  where SalesOrder = @Sord),'None')

It returns 'None' even though I know the data exists in the other database.

Can anyone help?

Try to put the ISNULL inside:
Select @Rep = ISNULL(Salesperson,'None') 
from SERVER.dbName.dbo.Table
where SalesOrder = @Sord

Hi Vitor,
Thaks for responding so quickly but I have solved it, the reason was the data was in different formats in the 2 databases, SalesOrder
Db1 123456
