calling RFC function

I am trying to call an RFC function in my bsp page. The RFC is to start a process chain. It gives me an error and I am not sure why. It tells me E_LOGID is not expected. Here is code:

if event->id = 'Update1' and event->event_type = 'click'.
      Call Function 'RSPC_API_CHAIN_START'
      DESTINATION 'NONE'
      importing
      I_CHAIN = 'NCNADMFULL'
      I_SYNCHRONOUS = ''
      I_SIMULATE = ''
      EXPORTING
      E_LOGID = 0.

      endif.
