The JavaScript below works when the form is empty but I also want to check another condition if the value is less then 10. How do I do this with my example code?
<SCRIPT language="JavaScript">
function validateForm(form) {

   if (form.TITLE.value == "") {
      alert("Your title is empty.");
      return false
   }
   
   if (form.STORY_BODY.value == "") {
      alert("Please enter story.");
      return false
   }

   return true
}

</SCRIPT>

Use : form.STORY_BODY.value.length < 10
<SCRIPT language="JavaScript">
function validateForm(form) {

   if (form.TITLE.value == "") {
      alert("Your title is empty.");
      return false
   }
   
   if (form.STORY_BODY.value.length < 10) {
      alert("Please enter story.");
      return false
   }

   return true
}

</SCRIPT>
