Hi everyone & thanks again for the great advice I always get here. This is an awesome community.

I am having a bit of trouble that I hope someone will be able to help me with - I keep thinking the answer is obvious, but I just don't have the experience yet to figure it out on my own.

I have a list of automatically generated email addresses and names with checkboxes next to each name. When a user selects a name that value (person) is automatically added to an email that is sent when the user hits a send button. I would like to add an input field that would allow the user to enter email addresses not found on the list, but am unsure how to grab the value and have it added to the checkbox list values. I do not want the value to be permanent - it should be disgarded as soon as the email is sent.

Code is below - thank you so much for any advice or guidance.

Shannon
