I have a pdf document with text entry field where users will enter numbers. I then have a Total Score field where I want to calculate the following:

(Score1+Score2+Score3+Score4+Score5+Score6+Score7)/45

I then want to Round that number to the nearest integer.

In the Calculate tab or the Total Score text field properties, I assume I need to either use the 'Simplified field notation" or "Custom calculation script" to achieve this but I can figure it out and don't know javascript well enough.

Could anyone off help?
