[Closed] making a pflow button

Hello every one

  I'm pretty green when it comes to scripting so plz bare with me. :)
  
  I'm trying to make a button that makes a PF_Source...Seems simple enough, I can make the script that makes the PF_Source and when you go to the ParticleViewer it shows up correctly,renders particles and displays them in the view port . But if I try to put that code into a button it creats the PF_Source but the "Render" and "Display" operators dont seem to work any more.
  
  This code makes the  PF_Source

    pf=PF_Source()
      --pf.Enable_Particles= true		
      
      
      particleFlow.beginEdit() 
      	
      
      ev=event()
      br=birth()
      	
      	pf.appendInitialActionList ev
      	ev.appendAction br
      	ev.appendAction (Position_Icon())
      	ev.appendAction (Speed())
      	ev.appendAction (ShapeStandard())
      	ev.appendAction (DisplayParticles ())
      	pf.appendAction (RenderParticles())
      	 
      
      particleFlow.endEdit() 

 and this is so post  to be it with the button

rollout Rollout1 "particle flow tool box" width:200 
     (	
     	button pflow "Pflow"
     	on pflow pressed do 
     		
     	(
     pf=PF_Source()
     --pf.Enable_Particles= true		
     
     
     particleFlow.beginEdit() 
     	
     
     ev=event()
     br=birth()
     	
     	pf.appendInitialActionList ev
     	ev.appendAction br
     	ev.appendAction (Position_Icon())
     	ev.appendAction (Speed())
     	ev.appendAction (ShapeStandard())
     	ev.appendAction (DisplayParticles ())
     	pf.appendAction (RenderParticles())
     	 
     
     particleFlow.endEdit()  
     
     
     	)	
     	
     )
     createDialog Rollout1	

any ideas would be great for I have run out :bowdown:
