	Setting up user inputs


	Now add an ON input ( Blue) port to the Pstorm node

			And link the Bool output to the on port


	OK for this exercise we will be adding user data fields to the actual xpresso tag in object manager so at the top left of the xpresso window click the blue input box


	Choose time from the list of available ports


	It shows up blank so rename the port by right clicking at set it to Start


	To see port names right click at the top of the xpresso window and choose ports - show names


	Add another time port and rename it to stop


	Now in the attribute manager for the xpresso tag you can se the 2 data input fields


	We need to connect these 2 ports to the Input 2 ports of the compare nodes


	Change your start and stop to whatever takes your fancy ( these are frames)


	Now we need to set the top compare to be >= greater than or equal and the bottom one to <= less than or equal. Check that the data types are Real. The Bool should be set to AND

There you have it, a basic setup for changing the start and stop times of the emitter via the attribute manager

In the next pages we will look at placing user data fields directly onto the null object
