Once you have modified information on a form, you must save it in order
for your changes to be available. Use the save button located toward
the bottom of the screen to commit your changes.
When you first arrive at a screen with editable fields, the save button is
dimmed out (see the image, below). When the save button is dimmed out, you
may not click on it.

When you change information on the screen, the save button is un-dimmed,
allowing you to click on it and save your changes (see image, below).

When you click on the save button, you are always asked if you want to save
your changes. Click on the OK button if you want to save your changes or the
Cancel button to back out of the save operation.
Warning: if you do not use the save button,
you will lose your changes when you leave the page.
