I thought I got this working but just found realized it is not working. So I think I was mistaken.
Figured it OUT this works....
var dName = Appery("DateName"); 
 var dNameVal = dName.val(); 
 var getval = Appery("LogDate"); 
 getval.val(dNameVal);
I knew it was something simple I was missing! 
Does This matter?
DateName format = DD, d MM, yy  (I use this to Display with List/Query) 
 LogDate format = mm/dd/yy   (I use this to Sort List/Query)
Otherwise The List does not sort chronologically if I just use DD,d MM, yy format.
Tried correcting JS with this:
var DateVal = DateName.val(); 
 var ChangeDate = Appery("LogDate"); 
 var getval = ChangeDate; 
 getval.val(DateVal);
Am I in the Ball Park?
It worked! Thank you so much! I was on jquery searching for examples on traversal and filtering. Can't tell you how much this helps. Thank you!
