A problem with *nc float file

[aearamos]

Hello everyone.

I have defined floats in my *.h file, I have put the correct floats file in the *in and I have generated the *flt.nc file. But whenever I read the *flt.nc file with ncload it has no data written on it. My values of lat/lon/temp/salt/depth are all 1.000 and I just can't plot any float trajectory. I'm actually using 1800 floats being 900 following the lagrangian trajectory type and 900 the isobaric type. I'm using Fz0 as negative. Can anyone tell me whenever I have to use it positive?
I'm adding my floats file so you can see if I did anything wrong.

Thanks.
