changing values on a webpage

So I'm trying to get my parallax servo controller card to interface with a webpage.
I can get the webpage to change variable values and move the servos, with getvariable and setvariable. But I can't get the servo position to go to the webpage. For example moving a slider to show the position of the servo. Is there a vbscript command that I'm missing that will change a value on the webpage? Or what would you recommend I do so that I can have roborealm feed variable values to the webpage that aren't only in the video feed screen? Thanks

spacehermit,
If you download 2.15.2 we included a short example in the index.html file that shows how to use the get_variable to update the image count. Note that this example uses a 1 sec polling to get that information. Hopefully you can see how to extend this to your usage.
Note that the returned variables are in Javascript format and executed such that a new variable with the appropriate value is created. This is a nice way to avoid having to parse the variable information on return.
Note that you should backup your index.html before re-installing RR over your current install otherwise you may lose any changes you have made to the index.html file.
STeven.
