The only script I can find to move objects is very old and doesn't work

I want to be able to move an object by set X & Y amounts, e.g. 2.1mm down and 5.35mm sideways. I found a script here that claims to do that. It's for CS3 so I put it in a folder called Version 5.0 Scripts. The error it returns is this:

//

var s = app.selection[0]

function moveObjectBy ( s , 2.1 , 5.35 , 'mm' ) {

//-------------------------------------------------------------------------

//-- M O V E O B J E C T B Y

//-------------------------------------------------------------------------

//-- Generic: Yes for Adobe InDesign CS3

//-------------------------------------------------------------------------

//-- Purpse: To move the passed object down and to the right by the

//--  specified amount in the passed unit values.

//--  The significant thing here is that you do not need to worry about

//--  the current measurment system in use on the Adobe InDesign page.

//--  Another benifit of this routine is that some special objects

//--  can be constructed via plug-ins which prevent them from having

//--  thier bounds manipulated. Ads on MediaSpan jazbox pages are

//--  one of these types of objects.

//-------------------------------------------------------------------------

//-- Parameters: 4

//--  o: The Adobe InDesign object to move. There are many things

//--   that can be moved. Any page item ( text frame, graphic

//--   frame, unassigned frames, graphic line, group, etc. If

//--   it can be modified using controls in the Object menu in

//--   Adobe InDesign, likely it can me moved by this function.

//--  down: The amount to move the object down. If you want to move

//--   the object up, then use a negative value.

//--  right: The amount to move the object to the right. Again, use

//--   a negative value to move the item to the left.

//--  unit: A string. Can be any of a large number of choices.

//--   For example: 'pica', 'point', 'mm', 'centimeter', 'inches'

//--   or 'pc', 'pt', 'millimeters', 'cm', 'i'

//-------------------------------------------------------------------------

//-- Returns: True if successful. False if something prevented the item

//--  from moving. For example, locked objects cannot be moved.

//-------------------------------------------------------------------------

//-- Sample Use:

//~   var s = app.selection[0]

//~   moveObjectBy ( s , 0 , 2.54 , 'cm' ) // right 1 inch

//~   moveObjectBy ( s , 3 , undefined , 'picas' ) // down a half

//~   moveObjectBy ( s , 0 , -1 , 'in' ) // back to the left 1 inch

//~   moveObjectBy ( s , -36 ) // return to the starting place

//-- Verify there are good numberic values for down and right or set to 0

if ( isNaN ( down ) ) { down = 0 } ;

if ( isNaN ( right ) ) { right = 0 } ;

//-- Assume points (my favorite for scripts) if the unit isn't passed.

if ( unit == undefined ) { var unit = 'points' ; }

//-- Make sure that we passed a lowercase value.

unit = String ( unit ).toLowerCase() ;

try {

  //-- Convert to ExtendScript unit values. This is unique to

  //--  ExtendScript and is not part of JavaScript or ECMAScript.

  //--  Note, there appears to be a bug in how this works. Picas

  //--   converts to 'pc' and move won't take that, so back to

  //--   picas the string will be converted.

  var downUnitsToMove = String ( new UnitValue ( down , unit ) ).replace ( 'pc', 'picas') ;

  var rightUnitsToMove = String ( new UnitValue ( right , unit ) ).replace ( 'pc', 'picas') ;

  //-- Most objects support a .move method. Try it then return true.

  o.move( undefined , [ rightUnitsToMove , downUnitsToMove ] ) ;

  return true ;

}

catch (err) {

  //-- if any of the conversions to unit values failed or if

  //--  the passed object cannot be moved this way, then

  //--  return an error.

  return false ;

}

}
