OT: JS number check

[Robert Orlini]

I need a _javascript_ later to come up when anything but a number and/or a decimal point is entered into a price each field. The _javascript_ below is not allowing the decimal point. Can anyone suggest what I have to add or fix please?

function isNumber2(inputStr, field)
{
for(var i=0; i<inputStr.length; i++)
{
var charVal = inputStr.substring(i, i+1);
if(charVal < "0" || charVal > "9" || (charVal.value=="" || charVal.value ==",")) {
alert ("Please make sure your " + field + " entry are numbers only");
return false;
}
}
return true;
