Hi. I'm a web design student, and I'm having trouble with my javascript assignment. The assignment is to:

"calculate an employee's weekly gross salary, based on the number of hours worked and hourly wage entered by the user; compute any hours over 40 as time-and-a-half; and display the results in an alert dialog box."

My form and alert messages seem to working fine but nothing calculates. You can view the page and source code here:

Any and all help appreciated!

that's because the variables are set as the page loads AND before the form elements even exist.
