/* 

8/18/2005 Updated
  Added checkTime function to check valid time values with
  or without the AM/PM

5/16/2004 Updated
  Enhanced currency checks to use RegExp as well as enhancing the 
  integer and currency checks to use the intMin and intMax
  values to test the values of the number as opposed to the length.
