Thanks Joe and r ganesh. Can I use this method to also remove an element of the array? Ie:

1. User types into textbox and clicks go.
2. User makes a mistake and needs to remove the last element they entered, this would be the value in the textbox.

Thanks for your help guys
interrupt

You will populate the array when user click Go button right and also set the value of textarea.
So if user modifies anything in the textbox,repopulate the array by clicking the Go button.
