Two active transformations cannot flow into a passive transformation in Informatica Cloud

[chintu123]

I am facing an issue with Informatica Cloud. I am very new to the system. I need to parse a XML which has various nodes in it. For this I have used a Hierarchy Parser and from that to a Sorted output and used Joiner to join different nodes in the XML. Since there were different Joiners, I have clubbed them into a singe Joiner and send the output to the Target. But I am getting an error Two active transformations cannot flow into a passive transformation.. Informatica cloud help provided me the below link [ERROR: "Two Active transformations cannot flow into a passive transformation" while validating a mapping in IICS][1]

[1]: but I am not sure which is the Passive Transformation here. I am using only Source, Hierarchy Parser, Sorted Output, Joiners and Target. I am in a critical situation. So any help will be much appreciated.
