    // Basic Element Animator (11-May-2009)
    // by Vic Phillips http://www.vicsjavascripts.org.uk
    
    // To progressively change the Left, Top, Width, Height or Opacity of an element over a specified period of time.
    // With the ability to scale the effect time on secified minimum/maximum values<br />
    // and with three types of progression 'sin' and 'cos' and liner and an optional 'Bounce'.
    
    // **** Application Notes
    
    // **** The HTML Code
    //
    // when moving an element the inline or class rule style position of the element should be assigned as
    // 'position:relative;' or 'position:absolute;'.
    //
    // The element would normally be assigned a unique ID name.
    //
    
    // **** Executing the Effect(Script)
    //
    // The effect is executed by an event call to function 'zxcBAnimator('width#',document.getElementById('tst'),10,800,5000,[10,800],'sin');'
    // where:
    //  parameter 0 = the mode(see Note 2).                                                                     (string)
    //  parameter 1 = the unique ID name or element object.                                                     (string or element object)
    //  parameter 2 = the start position of the effect.                                                         (digits, for opacity minimum 0, maximum 100)
    //  parameter 3 = the finish position of the effect.                                                        (digits, for opacity minimum 0, maximum 100)
    //  parameter 4 = (optional) period of time between the start and finish of the effect in milliseconds.     (digits or defaults to 2000 milliSeconds)
    //  parameter 5 = (optional) to scale the effect time on a secified minimum/maximum.                        (array, see Note 5)
    //                 field 0 the minimum. (digits)
    //                 field 1 the maximum. (digits)
    //  parameter 6 = (optional) the type of progression, 'sin', 'cos' or 'liner'.                              (string, default = 'liner')
    //                 'sin' progression starts fast and ends slow.
    //                 'cos' progression starts slow and ends fast.
    //
    //  Note 1:  The default units(excepting opacity) are 'px'.
    //  Note 2:  Examples modes: 'left', 'top', 'width', 'height', 'opacity.
    //           For hyphenated modes, the first character after the hyphen must be upper case, all others lower case.
    //  Note 3:  To 'toggle' the effect include '#' in parameter 0.
    //           The first call will set the toggle parameters.
    //           Subsequent calls with '#' in parameter 0 and the same start and finish parameters will 'toggle' the effect.
    //  Note 4:  The function may be re-executed with a different set of parameters (start/finish time or period)
    //           whenever required, say from an onclick/mouseover/out event.
    //           The period parameter will be retained unless re-specified.
    //  Note 5: parameter 5 is of particular use when re-calling the effect
    //          in mid travel to retain an constant rate of progression.
    //  Note 6: parameters 2 and 3 must be different values to execute the script.
    //
    
    
    // **** Functional Code - NO NEED to Change

    Hey that last attempt worked really well! I tried to break it in several browsers and couldn't. I think this could be exactly what I need to get started. Thank you both very much for the assistance!
