Python: Error with if-statement

start = end
  end = 450
  split = 413

for frameNum in range (start, end):  # frames 0 .. 9
  if frameNum <= split:
    space = makePicture(getMediaPath("space.jpg")) #1229 x 692 pixels 
    rocket = makePicture(getMediaPath("rocket1.png")) #74 x 139 pixels
    copyInto(rocket,space,614,553 - frameNum*2 + 2*start)
    writeFrame (frameNum, directory, space)
y = 553 - 2*split + 2*start   
  if frameNum > split:
    space = makePicture(getMediaPath("space.jpg")) #1229 x 692 pixels 
    rocket = makePicture(getMediaPath("rocketWOflames.jpg")) #74 x 139 pixels
    addOvalFilled (space, 150 + int(30*math.cos(1*frameNum/2)),150 + int(20*math.sin(1*frameNum/2)), 70, 30, red)
    copyInto(rocket,space,614,y)
    writeFrame (frameNum, directory, space)

The place at which I am having trouble is "if frameNum > split:"

Here is the error message:

Invalid syntax
Your code contains at least one syntax error, meaning it is not legal jython.
The error is on line 94

I checked the indentation--it appears to be correct; I tried replacing the if-statement with else--didn't work. Can anyone spot the error?
