repeat for each is read only, but you try to change tFilePaths on the fly :-)

Do this:

on dragEnter
 put the dragData["files"] into tFilePaths
 set the itemDel to "."
 repeat for each line L in tFilePaths
   if (last item of L is among the items of "GIF.JPG.JPEG.PNG") then
    put l & CR after tFilePaths2
  end if
 end repeat
 delete char  -1 of tFilePaths2
 set the dragData["files"] to tFilePaths2
 put the dragData["files"] --> Value does not get updated!
end dragEnter
