sql error trying to change field

What am I doing wrong in this code?  It says incorrect syntax near '=' by importstatus.

USE Data1;
SET ImportStatus = 'U';
from THeader
WHERE     (Invoice= 'credit') AND (DateTime >= '2014-09-9') AND (DateTime < '2014-09-15');

Several things :-) - Can you try the following (note the "GO", the "UPDATE" line, and the lack of a semi-colon at the end of the "SET" line:

Use Data1
GO
UPDATE THeader
SET ImportStatus = 'U'
WHERE     (Invoice= 'credit') AND ([DateTime] >= '20140909') AND ([DateTime] < '20140915');
