Bill Message
In the Bill form you can have a custom message appear on the printed Bill. This is a good way to enter a specific message about the selected Bill. There will be one of two slightly different buttons displayed on the Bill form depending if a message exists or not.
This button will appear if there are no messages entered for the selected Bill. Clicking this button will open the Bill Message form, which will allow you to enter a message for the selected Bill. When you are done entering a message, click on the X button at the right hand corner to close the form and return to the Bill form.
If this button is showing in place of the normal message button then it means there are existing messages for the current Bill. Clicking this button will open the Bill Message form displaying the previously entered message for the selected Bill. When you are done editing or viewing that message, click on the X button at the right hand corner to close the form and to return to the Bill form.
