I am making a form to determine the weighted GPA of up to 9 courses and I want to find a way to have the calculation ignore a course line for which there is no grade (this may be the GPA of anywhere from 4 to 9 courses). I'm having problems entering some blank field on the letter grade export value that doesn't calculate to "0", which of course would skew the GPA. From the grade points and number of credits, I will have the PDF calculate weighted grade points, divide that by the total credits to give me a GPA. I'm using Adobe Acrobat Pro DC on OSX 10.12. Thanks in advance for any answers.
