My form is configured to pop up an alert box when conditions are met. In the first function allotment, the alert box appears twice. I don't know why this would be.

$(document).ready(function() {
	$("#Field20").on('change', allotment);
    $("#Field47").on('change', evaluate);

	function allotment(){
		var ToDate = $('.ToDate input').val();
		var house = $('.total input').val();
            
		switch (true){
			case house == 1:
				var allow = 50;
				break;
			case house == 2:
				allow = 65;
				break;
			case house == 3:
				allow = 80;
				break;
			case house == 4:
				allow = 95;
				break;
			case house >= 5:
				allow = 110;
				break;
		}
		var availablePoints = +allow - +ToDate;
		alert("This guest has " + availablePoints + "/" + allow + " points remaining this week.");
      return false;
    }
  
  function evaluate(){
        var house = $('.total input').val();
        var cart = $('.cart input').val();
        var savedCount = $('.ToDate input').val();
        var newCount = +cart + +savedCount;
      
         
      if (house == 1 && newCount < 50) {
        alert("After today, there are " + (50 - newCount)
              + " food points remaining for the week.");
        
      } else if (house == 2 && newCount < 65) {
        alert("After today, there are " + (65 - newCount)
              + " food points remaining for the week.");
              
      } else if (house == 3 && newCount < 80) {
        alert("After today, there are " + (80 - newCount)
              + " food points remaining for the week.");
            
      } else if (house == 4 && newCount < 95) {
        alert("After today, there are " + (95 - newCount)
              + " food points remaining for the week.");
      
      } else if (house >= 5 && newCount < 110) {
        alert("After today, there are " + (110 - newCount)
              + " food points remaining for the week.");
            
      } else {
            alert("The maximum number of food points have been reached.");
        }
}  
});
