Calculate not working on a form - Javascript disabled in our Adobe Pro

Hi, I have attached a simple time sheet that I would like to use to calculate the regular hours of staff. Very simple sum calculate. However whenever I save and re-open the file, the function does not work. I have followed all the suggestions here but none of them work. Also, the Adobe Pro that we are using are disabled from using javascript, could this be the reason?

Thank you to whoever can pin point what I'm doing wrong or tell me what's going on.

The only text box that has the calculate feature is the "Reg HrsTOTALS" text box at the moment.
