I am trying to figure out the best way to complete a task. Here is what I'm trying to do:

Enter this information into text box one:

12345

Have text box two display the same information like this:

one, two, three, four, five

This should be able to accomplish this in any numeric order with the trailing comma left off after the last digit.

Can anybody give me some help or point me in the right direction? Thanks in advance!!!
