I need to ensure the minimum answer is 5 and the maximum can be no larger than 25. The code I use is:
function temp(form)
{
var i = parseFloat(form.Inc.value, 10);
var c = 0;
c = 25 - ((300 - i) * 8.0 / 100);
form.Fee.value = c.toFixed(2);
function decrease(form)
{
if (c > 25)
{
c--;
document.getElementById('Fee').innerHTML = 25;
}
}
function increase(form)
{
if (c < 5)
{
c++;
document.getElementById('Fee').innerHTML = 5;
}
}
}
However the answer box in the form doesn't recognise the minimum and maximum figures.
