Hi Francisco;

Infact the last line which says Count=3D0; is required because, the size
of the dropdown box keeps dynamically decreasing as and when i remove an
option from it.

In the same example,the size of the select2 box is initially 4, and when
the loop executes for the first time,one option si removed from the
dropdown box.Noe when it checks the for condition again, the size will
be 3.
If count were not equated to zero, then the for condition looks
something like this:

for(Count=3D1;Count<3;Count++)

and for the next iteration it will be :

for(Count=3D 2; Count<2;Count++)

and the code will not be executed after this which results in only two
of the four values being removed from the
dropdown box and this is definitely not something that is required.

Thanks and Regards,
Nitin.

3D error


Hi! Regarding the strange 3D characters in the code,
very often the mailers systems need to mask some symbols,
like the equal sign or the quotes, so they convert them
to something different. Is too bad that not all of the
programs talk the same, and do not know how to change back.

Simply ignore the weird codes to get a sintactically
correct program. By example, I edited the first function
dropping the 3Ds (sorry if some dumb program insert them
again!):

Note that the last line using the Count variable must be deleted because
resets the for condition, so Count will never reach the length value!

Sorry, I could not check the full code!
