MX multiple strings to dynamic textfield

I have multiple mc’s that contain input textfields. I want the results of these to appear one after another in the same dynamic textfield. Later they will be sorted alphabetically.

So far, I’ve been able only to get one item to appear at a time in the dynamic textfield–the next item replaces the first. A for loop didn’t work.

Can anyone point me in the right direction to get the new text string to be added to the previous text string rather than to replace the first text string?

Anything at all similar I’ve seen creates a shared object instead of writing multiple strings to one dynamic text field.

Thanks for any help you can give me.
