Question: Is there some way in your dynamic text boxes that after you click a button the text box doesn't disappear
Answer: The text box is set to not appear by default ie. before your visitors start entering anything. Wherever you want to have the the textbox continue to appear after a button within the form you need to add to the code processed by the button to test the value of the selection list. The code that you need to add is the same as is contained in the onchange parameter on the selection list. Just add the call to toggleOther to the code executed by any action where the text box unexpectedly disappears and that should correct the problem.
