Validating 3 fields

Hi,

 I am trying to build a custom validator to validate 3 fields: Min < Most Likely < Max.

 I've written this custom validator, but for some reason, most of the time, the value of "Max" is being read as null and no error messages are displayed. Is there something wrong with my code:

 Thanks,
