Main changes are

      $("#red").find(".ui-slider-handle").html('<span class="but">'+red+'</span>');
      $("#green").find(".ui-slider-handle").html('<span class="but">'+green+'</span>');
      $("#blue").find(".ui-slider-handle").html('<span class="but">'+blue+'</span>');

      $("#hexVal").val("#"+hex);

Hi mplungjan,

Thank you very much for responding, I am sorry that it has taken so long to respond.

I was not aware you had answered, but I am working through your solution  and I have come across a bit of grief with the 1.10.3 css and js files but I am working through the issues no problem.

I will be in touch very soon

Thank you very much

John

Hi mplungjan,

I have installed Visual Studio 2012 on a laptop and tried to add wampserver, but can't get wampserver to run successfully and end up with an orange W in the tray.

I am considering removing VS 2012 and trying to install wampserver again and I am hoping to run your solution then.

I will get this done by Sunday

Thanks for your patience

John
