Commenting out large sections does not work sometimes

hi, im trying to comment out this text:

 Write a MATLAB script that will load a *.csv (comma separated value) file containing
two column vectors; the first vector containing time values, the second amplitude
values. The script should compute the discrete fast Fourier transform of the amplitude
values and plot the Single-Sided Power Spectrum. MATLAB help can be found
at:

but %{

%} does not work. this happens sometimes. would you know why?

Are there special rules for block commenting?

This works when nothing is written next to them....you must write the comment after and before these lines:

The below works:

I did exactly that and only the first line was commented out. its not a big problem

Check it once.....or attach the file here which didn't work.

my bad, the %{ was not on its own line. simple error

[KSSV]

I knew it..so only asked to attach the file....;)
