1) You don't need the .search() to get the values from the textboxes
2) You should use an or ("||") to test weight values ......  if (80 > pos || pos > 300) {


function chkAge() {
      var myAge = document.getElementById("custAge");

      //Test the format
      var pos = myAge.value;
      if (pos < 18)      {



// Checking the Weight for correct format

function chkWeight() {
      var myWeight = document.getElementById("custWeight");

      // test format
      var pos = myWeight.value;
      if (80 > pos || pos > 300)      {
