Make "VALUE" field more self-explanatory. Depending on the selected metric, there should be some kind of explicit hint what and in what format should be entered in the input. Add an example inside of the field, tooltip, etc.
There are some options that become irrelevant under certain conditions, e.g. timeframe and alert frequency for >0 poor calls, call volume exception for number of poor calls or legs, target value for company wide target, etc.
