/***********************************************
 The clear fields function is used to clear fields  that are no longer valid. 
 For example, there may be  a list of four radio buttons, if you check on 
 button then you you can fill out options for that context, however if you check 
 the other button you will have other fields to fill out. This function clears the 
 fields of the option that isn't checked. 
 
 Arguments: 
 	The first argument is the index of the field that is checked
	The Second is a 2 dim array, the first dimension is the radio buttons, 
		the second dimension is the fields valid for that option
