Invalid column name error

I am having a problem with an error message.
When I try to drag the last name field from the table under Cottages(this is the name of the database on SQL Server from MSDE it was taken from a student files disk), I get an error message:
 
Data Adapter Configuration Error
 
The wizard detected the following problems when configuring the data adapter for "Guests".
Details:
 Generated SELECT statement
 
Invalid column name 'Last'
 
I can cancel or click OK
When I click OK, I get the Connection and Data Adapter Components in the component tray.  I can name them.
But when I try to generate the dataset, I get another error message.
 
Microsoft Development Environment
 
Retrieving the schema for daLastName failed
 
Invalid column name 'Last'
 
I can click cancel or OK
 
When I click OK I get the Generate Dataset box
I can name the dataset, but there are no tables to choose from in the box below
I am in the design view of the guests( I will be adding textboxes and a combo box to display info from the database) form. The guests form is a child form
What am I doing wrong
Thanks, Kay

The problem is that "last" is a reserved word for SQL Server / MSDE.  

The easiest fix is to rename the table "last name" to "last_name" or "LastName".  This way the table name won't be parsed into two pieces.

Note however that this will break any triggers or stored procedures that referenced this table so they'll need to be fixed (there probably aren't any though because they would likely have already choked on the 'last').

this will also work.
[last name]

NetPointer,

The brackets will work if you're writing the code by hand but it sounds like Kay is using Visual Studio and dragging the table.  This means the IDE is throwing an error right away.  

Of course you can still edit the sql manually but why bother with drag-n-drop if you're going to that?
