Hi Franco!

You will never reach any code inside the  for-block
If i=3D1 i can't be 31
I think you ment:

for(i=3D1;i<=3D31;i++)...

if you use elements[...] a string inside the brackets is expected. 
Therefore
you simply need to concat the two substrings. If "MornHourArr" is a 
constant
string:

if(FormButton.elements["MornHourArr"+i].value>23)

Greetings Hans
