Those issues aren't that hard to solve!

• Validation of numbers (for example, it will allow "text" as a valid height measurement)
  

  Javascript code:

  ---

  var sFoo = "85.1";
  var nFoo = 1 * sFoo; //Attempt a string to number conversion
  if( isNaN(nFoo) ) nFoo = 0; //Failed, set to some default value or ignore the declaration

  ---

• Validation of matching IDs (for example, two controls with the name "EdtTest")
  

  Javascript code:

  ---

  var sTestId = "BtnTest"; //Control ID to test
  var bIsUniqueId = true; //Boolean to hold the result
   
  for( var i in WndLstId ) { //Loop through the control IDs
      if( WndLstId[i] == sTestId ) { //Check if this control ID matches the test ID
          //We have a match!
          bIsUniqueId = false; //Set the result to false
          break; //End the loop (we know it's not unique now)
      }
  }
  //Now make use of bIsUniqueId for further processing
