Hog 1K fixture library

I have written a patch for a moving mirror for use on my Hog 1K, it happens that the fixtures intensity is inverted (ie at 100% it is closed at 0% it is open) i was wondering if there is any way on inverting this either in the desk or in the actually fixture template.
Comments
parameter = Intensity
default = 0
highlight = 255
crossfade = 0
type = htp8bit
range = 0,255,%
The most important thing for you to check here is the "range" entry. This specifies the min value, max value, and display unit for the parameter. If you're finding that intensity is inverted, you should start by swapping your min and max values on this line.
I hope this helps.
shall give it a shot, shall let you know how i get on
thanks
