Hi.
I have this custom button that works fine in regular UI but not in communities.  How do I make this work in communities.

{!URLFOR( $Action.FAE_Account_Allocation__c.New , null, [saveURL=FAE_Tracker_Entry__c.Id, retURL=FAE_Tracker_Entry__c.Id, CF00Nc0000001INF4_lkid=FAE_Tracker_Entry__c.Id , CF00Nc0000001INF4=FAE_Tracker_Entry__c.Name])}

Appreciate the help.
