eForm CC user based on choice

I’m currently using modx evolution’s eform to gather and submit registration data. However, I’ve ran into a stumbling block. I need the form to CC a certain person based on a checkbox in the form. If the checkbox has NOT been checked, it does NOT email this person. But, if the checkbox IS checked it will email them. Any ideas???

Sounds like a job for the &eFormOnBeforeMailSent event. See documentation included with the snippet (eform/docs/eform.htm). You could create a function to test the checkbox field and add a &cc field if it’s set. Or maybe set the &cc field in the snippet call, and clear it if the checkbox isn’t set, to make updating it simpler.
