forms – JavaScript – validate numeric only and within range

I have an asp form which has a number of fields. On submit I want to check, using javascript that a tickbox has been selected and that an \’amount\’ field in within a given range AND has numbers only. I\’m struggling to get it to check all three in one go – at the mometn i have the following:

<script type=\"text/javascript\">
function validateForm()
{
var x=document.forms[\"myForm\"][\"Amount\"].value;
if (x<5 || x >250)
  {
  alert(\"Please complete all required fields - Amount you wish to save\");
  return false;
  }

else if ( myForm.agreesubmit.checked == false )
  {
  alert ( \"You Must Agree To The Terms and Conditions\" );
  return false;
  } 

}
</script>

At the moment this is two seperate checks for tick box select and range.

Any ideas appreciated.
