Yes, indeed there are a few lines missing. Just the read file and the i=0 pretty much. The help you gave me solved my problem, thank you very much!
I know the calls to float() are sub par and quite stupidly made but I'm not that good at python scripting (yet) so I try to keep my functions rather easy to read so I understand what is happening. A bit later I will take the time to make my code more sophisticated, but as of now I just want it to work, hehe.
Again, thank you so much!
