Trying to control 2 RGB LED's using the Ajax example in the Webduino library

Hi all, I am just playing around with the Web_AjaxRGB_mobile sketch in the examples and trying to control 2 LED's

I have duplicated the bits I thought I needed to and added variables for a second LED. It compiles and looks OK on a browser (two sets of silders show up) but I can see through the serial monitor that the values for reda, greena, bluea, redb, greenb and blueb don't update. I'm really stuck now, what have I missed?

Thanks

Any ideas, I'm mega stuck on this :frowning:

      repeat = server.readPOSTparam(name, 16, value, 16);

      if (strcmp(name, "reda") == 0)

Seems like this would be a good place for a Serial print of what is contained within name and value.
