twe = s(form.twe.value, 20);
ten = s(form.ten.value, 10);
fiv = s(form.fiv.value, 5);
two = s(form.two.value, 2);
one = s(form.one.value, 1);
hlf = s(form.hlf.value, .5);
qtr = s(form.qtr.value, .2);
dme = s(form.dme.value, .1);
nck = s(form.nck.value, .05);
sxw = s(form.sxw.value, .02);
pny = s(form.pny.value, .01);
