MS SQL Server 2008 doesn't like my inputs

if there is any foreign key field in that table make sure its reference else hit enter after input

the exclamation mark is "NOT" the problem.
please show the error you get, and the table structure, and any triggers you might have on the table.

All these *@#& widget ding dangs are driving me crazy.  I'm not 100% sure where to find what you are talking about, but I was trying to make a few FK/PK relationships.  The red exclams are on fields that I didn't think I create such things.  Here I show you a second table, that should be at the top of the tree
or whatever, no FK problems  Automobile is linked to Customer by purchased_by which
is equal to PK license in Customer.  It doesn't seem to like my Customer either.  I also made a Sales_Rep I need PSmith I haven't created him yet, but I don't know why that should affect Customer

There are no errors in this error window

Everything disappears when I press exclam "execute SQL"

here is another file

Lots of nice pictures about this same database here:
