Adding a PlayMacro action

Outside of a Condition element:

You can add only one PlayMacro action to a macro script, and that PlayMacro action must be the last action in the Actions list (<actions> element) of the macro script.

Inside a Condition element:

You can add one PlayMacro action to the Condition is True branch (<if> element), and that PlayMacro action must be the last action in the branch (<if> element).
You can also add one PlayMacro action to the Condition is False branch (<else> element), and that PlayMacro action must be the last action in the branch (<else> element).

You can have as many Condition elements in the macro as you like, with each Condition element containing one PlayMacro action in its Condition is True branch and one PlayMacro action in its Condition is False branch.

The Macro Editor and the Code Editor enforce these rules.
