function calculator() {
var val1 = theForm.txtval1.value;
var val2 = theForm.txtval2.value;
var math = document.getElementById("math").value;
theForm.Total.value = math;

if (math == "add") {
document.getElementById("Tol").value = val1 + val2;
}

if (math == "minus") {
document.getElementById("Tol").value = val1 - val2;
}

if (math == "times") {
document.getElementById("Tol").value = val1 * val2;
}

if (math == "divide") {
document.getElementById("Tol").value = val1 / val2;
}
}

When I use it, the subtraction, times, division are correct, but the sum always combines the numbers I entered together.
