>maybe my german bluntness, but " should be between 940 and 2000." for me sounds only to be a reccommendation, leaving me free to select the lower value if I realy desire (perhaps for running on a mobile device with limited screen area), so I was surprized that I was not able to save a lower value to try out. A message "value needs to be between" or "range is ... " would have been clearer in the way I would expect values outside 940..2000 not to be saved via validation.

The word range and value may be used in the message validation. I'll look into that.

http://mobile.levelextreme.com is also new and would evolve so that would probably be something to consider.
