Hi Experts,

I have the following code I got from an Expert. How can I incorporate a code to check if unitprice is a numeric value?


// form validation - make sure first name and
// last name fields are filled in by user
function validate()

if (input.length<1)
 alert("Please enter item price.")
 return false
else // fields populated
 return true
