Results file is empty except for the column titles

[vruellot]

Hello,

I have limited experience with Praat scripts and can't figure out what the problem is when I run this script. I get a results file that is empty, except for the title lines (i.e., Filename, Segment, label, F1 (Hz), F2 (Hz), F3 (Hz)). Apparently, the script stops working after line 45, although I never get any error message (I did, before I replaced the underscore between "5500" and "(=adult female)" with a space).
Is there something else somewhere in the script that I need to modify?
Many grateful thanks for your help!
