     function checkForm()
          if(document.Check.Barcode.value == "")
               alert("Sorry, you must enter a barcode");
               return false;
          if(document.Check.Title.value == "")
               alert("Sorry, you must enter a title");
               return false;
          if(document.Check.Barcode.value.length > 5)
               alert("Sorry, the barcode can not exceed 99,999");
          if(document.Check.Title.value.length > 100)
               alert("Sorry, the title can not be more than 100 characters long");
               return false;
          if(document.Check.Author.value.length > 40)
               alert("Sorry, the author can not be more than 40 characters long");
               return false;

               alert("Sorry, the publisher can not be more than 30 characters long");
               return false;
          if(document.Check.Isbn.value.length > 20)
               alert("Sorry, the ISBN can not be more than 20 characters long");
               return false;
          if(document.Check.Publishdate.value.length > 7)
               alert("Sorry, the publish date field must be in the format YYYY-MM");
               return false;
          if(document.Check.Description.value.length > 500)
               alert("Sorry, the description can not be more than 500 characters long");
               return false;
          if(document.Check.Orderedby.value.length > 40)

          if(document.Check.Location.value == "0")
               alert("Sorry, you must enter a location");
               return false;
          var a = parseInt(document.Check.Barcode.value);
          var b = parseInt(document.Check.largestBarcode.value);
          if(a <= b)
               alert("Sorry, you must enter a barcode that is greater than " + document.Check.largestBarcode.value);
               return false;
</script>
<script language="JavaScript">
     function StripQuotes(){
     //This function will prevent double quotes from being placed around title
     var preamble = document.Check.Title.value;
     var strTitle = "";
     for (i=0; i < preamble.length; i = i + 1){
     if (preamble.charAt(i) == "\""){
          preamble.charAt(i) == "";
               }// ends IF
               else{var strTitle = strTitle + preamble.charAt(i);}
     }// ends FOR
     document.Check.Title.value = strTitle;
     }// ends StripQuotes() function
</script>
