//Standard Validation Javascript
//2003- Chris Marshall - Migrant Student Records System
//Sept '03 -- Added code to disable submit buttons when an error is thrown
//June 15th 2004 - Change /validates if date is 5 days in future or 2 years in past for Enrollments to 3 years
//Sept 14th 2004 pgw - Added ValNum2
