Add Button
Click the Add button, which is included if you specify the Update function, to create a new instance whose attributes equal the values of the corresponding controls. The new instance is added to the instances collection and the input fields are cleared ready for the next instance.
When you have added an instance, you can use the Next or Previous browse button to display the instance that follows or precedes the instance that has been added.
If you specify multiple instance display, a blank row is inserted in the instances table on the form and the new instance is specified in the blank row.
