To edit the text you would like to see previewed, first click on the
"Edit Text" link located above the column of text you would like to
edit. Once you click on that link you should see the dialog below...
This is called the "Edit Text" dialog. In this dialog you should see a
textbox labeled "Enter your new text (HTML Supported):". In this textbox
you can type in your new text (or HTML) which you would like like to see
previewed. After you've entered your text you have to decide which columns
you would like to update with that text. You can choose to update all 3
columns at once or update each column individually. Once you've finished
entering all of your text simply press the "OK" button to save your
changes, update the appropriate columns and close the dialog. If you
would like to close the dialog without saving your changes, simply
press the "Cancel" button.
