Small problem with checkpoint icon

[kuwalda]

I have a small part of my code here:

  
setElementData(thePlayer, "checkpoints", createMarker(_G[""..getElementData( thePlayer, "raceParticipate" )..""][ciga][1], _G[""..getElementData( thePlayer, "raceParticipate" )..""][ciga][2], _G[""..getElementData( thePlayer, "raceParticipate" )..""][ciga][3], "checkpoint", 6, 190, 156, 252, 250)) --works 
setElementData(thePlayer, "blips", createBlip( _G[""..getElementData( thePlayer, "raceParticipate" )..""][ciga][1], _G[""..getElementData( thePlayer, "raceParticipate" )..""][ciga][2], _G[""..getElementData( thePlayer, "raceParticipate" )..""][ciga][3], 0, 3, 190, 156, 252, thePlayer)) --works 
setMarkerIcon(getElementData(thePlayer, "checkpoints"), "finish") -- do not work 
setElementVisibleTo(getElementData(thePlayer, "checkpoints"), root, false) --works 
setElementVisibleTo(getElementData(thePlayer, "blips"), root, false) --works 
setElementVisibleTo(getElementData(thePlayer, "checkpoints"), thePlayer, true) --works 
setElementVisibleTo(getElementData(thePlayer, "blips"), thePlayer, true) --works 
setElementDimension( getElementData(thePlayer, "checkpoints"), 1 ) --works 
setElementDimension( getElementData(thePlayer, "blips"), 1 ) --works 
  

Why setMarkerIcon line does not work for me?

And what I am missing in here:

setMarkerIcon(getElementData(thePlayer, "checkpoints"), "finish")
