Try this code:

This funvtion will validate your result

function validateTester() {
    var flag = true
    var Tester = document.forms.Tester
    if (Tester.line1.value!="JavaScript") {
        alert("First box must say 'JavaScript'!")
        flag = false
        }
    if (Tester.line2.value!="Kit") {
        alert("Second box must say 'Kit'!")
        flag = false
        }
    if (flag) {
        alert("Form is valid! Submitting form...")
        document.forms.Tester.submit()
        }
    }
