Percentile Calcuation only if all scores are entered

[Laura24730199ig59]

I'm trying to get a percentage to show up ONLY if all of the fields are completed. I have 4 checkboxes, wth points assigned, but I don't want to calcuate the percentage unless everything is completed. Otherwise I would like it blank. Can anyone help?

A custom calculation script is required for this behavior.

What is the exact criteria that determines "everything is completed"?  Provide the form field names.
