Exclude project numbers from a query

[Hedy]

Hello, I have created a very simple/basic query and would like to exclude project numbers that begin with a "3."

Some project numbers begin with a 7, some begin with a "1," and some begin with a "3." The project numbers are also different lengths.

Examples/samples of the project numbers:

10175884 (8 integers long)
7651679 (7 integers long)
31724779 (8 integers long) NEED TO EXCLUDE THESE


I am working in Design View and would like to simply add a "not" statement to exclude the project numbers that begin with a "3."

Thank you

WHERE Left(myProjectNumber,1)<>3 ?
