I am trying to create my own space types and would like to change Space Infiltration Design Flow Rate. However, after doing so, the model gives fatal errors while simulation run:

*************** IDF Context for following error/warning message:
************* Note -- lines truncated at 300 characters, if necessary...
*************   4759 ZoneInfiltration:DesignFlowRate,
************* indicated Name=New_Infiltration_Rate
************* Only last 3 lines before error line shown.....
*************   4760   New_Infiltration_Rate,                  !- Name
*************   4761   Guestroom_Double Cottage,               !- Zone or ZoneList Name
*************   4762   ,                                       !- Schedule Name
** Severe  ** IP: IDF line~4762 Error detected in Object=ZONEINFILTRATION:DESIGNFLOWRATE, name=NEW_INFILTRATION_RATE
**   ~~~   ** Field [Schedule Name] is required but was blank**

What am I doing wrong?
