What's cond? If testing on velocity, then simply
if velocity >= 120;
h=msgbox('Your speed is okay');

'elseif' is a keyword; 'else if' is another else construction
Fixing that still leaves a problem--velocity can't ever be both > _and_
< 100 at the same time so the only time that can be satisfied is for the
single case of velocity = 100 exactly.
Perhaps the second 100 is a typo for 120 but in that case the <= should
be just < to make the two cases non-overlapping at exactly 120.

I'd also suggest looking at the CASE construct for another way to
construct such multiple logic...
