	Using JM_copySameAs
	This function is used to copy one set of fields to another set, and is usually used to copy
	a billing address to a shipping address.
	All paired fields must be similarly named for this to work, such as billCity and shipCity.
	Also, it is expected that a checkbox is used to toggle the copy on or off.
	The function allows for a variable number of arguments, 
	but the first three arguments MUST be the name of the check box, the first field prefix,
	and the second field prefix.  
	For example, JM_copySameAs('copybilltoship', 'bill', 'ship', 'FirstName', 'LastName', 'Address', ...)

	Using JM_validateDropdowns
	Usually, this function will be used in conjunction with the MM_validateForm() function

	The fieldList should be replaced by a list of the dropdowns that need to be validated in alternating field name, display name fashion, 
	such as JM_validateDropdowns('state', 'State', 'country', 'Country', 'birthMonth', "Month of Birth', 'birthDay', 'Day of Birth', 'birthYear', 'Year of Birth');

 Using JM_validateCheckboxGroup
 Usually, this function will be used in conjunction with the MM_validateForm() function 
 that Dreamweaver creates to validate a form.
 In this case, alter the onSubmit statement that is created to look like the following:
  MM_validateForm(args); JM_validateCheckboxGroup(fieldList); return (document.MM_returnValue && document.CG_returnValue);
 The fieldList should be replaced by a list of the checkbox groups that need to be validated.
 Each checkbox group will have four values associated with it.  
 In order they are minChecked, maxChecked, fieldName, displayName
 For example, JM_validateCheckboxGroup(1, 3, 'info', 'Information'); would force the user to check
 between 1 and three boxes.  For no min use 0, and for no max use -1.
