// This set of function are general includes for validation
// They are designed in pairs the validation and the event function
// the event function will call the validation with the event src



// The following functions initiate the functions needed to validate 
// various text fields.  A function with the following numbers in the
// name indicate:
//	1 - initiates the function for an HTML and SQL check
//	2 - initiates the function to check for a number with the maximum 
//		field length
//	3 - initiates the function to begin each word with a capital
//	4 - initiates the function to check for non-blanks
//	5 - initiates the function to make all characters upper case
//  vs_valid_phone_no - this function checks for numbers and to be sure
//		that numbers fill up every available character in the field
