Good day,

I'm populating 2 fields based on the Option set in a third one.
It works, but for some reason, sometimes when I change the entry from one value to another (from 3/01/2015 to 26/03/2016) , the field "# Volume" stays at the first position 
(149) and doesn't get updated... I tried both with Chrome and IE.
