Creating Conditional Macros
Sometimes you may want a macro to run only if some prior condition is met. For example, you could create a macro that prints a report only if the number of records to print is greater than zero. You can do this by creating a conditional expression, an expression that Access evaluates as true or false. If the condition is true, Access carries out the actions in the macro or macro group.

 | Click the Conditions button on the Macro Design toolbar. |
