if (document.forms[0].elements[0].value > max)
The above line can't do what you want. document.forms[0].elements[0].value
returns a string and you are trying to compare a string to a number. I'm no
expert but this should do it. HTH

function checkIt() {
alert(document.forms[0].elements[0].value + 3);
// if you entered 7 should = 73
// the above returns a string '7' and appends 3
alert( (+ document.forms[0].elements[0].value) + 3);
// if you entered 7 should = 10
// the + operator forces the string to an integer
