You have to say which table's VendorID column you want to evaluate your WHERE clause against (just as the error message says). Try this
WHERE (VendorJobs.`VendorID` = 13) As a shortcut , and to keep you from getting "typist's cramp", you only _need_ to specify the table name for columns that are NOT unique within the set of all columns in the tables you have joined into your query. For all uniquely named columns, you can drop the table specifier. Don't get me wrong, the way you are specifying your columns IS the **correct** method of being specific. I am merely suggesting a way for you to save yourself a few keystrokes and maybe a few typos along the way.
