What's cond? If testing on velocity, then simply
if velocity >= 120; h=msgbox('Your speed is okay'); > else if velocity >=100 & velocity <=100;
'elseif' is a keyword; 'else if' is another else construction Fixing that still leaves a problemvelocity 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 nonoverlapping at exactly 120.

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