How to build a list from an input field.

[etsmarines]

I would like to create a GUI form and have text box that i can type into and hit a button and it allows me to type another item in and starts creating a list that I can have pasted into an email when ready.

Ex.

I want to type in two different inputs (days for example) Monday and Tuesday and a list of those manually entered values starts to show up with the days that I am entering in the single text field

Monday
Tuesday

if i enter Wednesday and hit enter the list below the text box or in a variable will now be

Monday
Tuesday
Wednesday

And when i create an email within the save script i can have it insert that list as

Monday
Tuesday
Wednesday

or whatever the manually created list in the GUI form was.

Thanks for the help!
