How do I use a variable in a function from a previous function?

[system32]

I am having very much difficulty trying to use a variable that I made in a previous function to work with my new function. I have tried to make the variable global but this is not working and I have no idea why. Can anyone please help me out?

Thanks

You'll have to provide some code before we can tell you what went wrong.

[system32]

here is my Javascript code:

	function checkProvince()
	{
		var myForm = document.pizzaForm;	
		if (myForm.province.value == "Nunavut" || myForm.province.value == "Yukon")
			{
				alert("We are sorry but we do not deliver here.");
			}
	}
	
	function checkName()
	{
		var errMessage = " ";
		var checkk = 0;
		var myForm = document.pizzaForm;
		var rePhone = /^\(?(\d{3})\)?[\.\-\/\s]?(\d{3})[\.\-\/\s]?(\d{4})$/ ;
		var rePostal = /^[A-Z][0-9][A-Z][0-9][A-Z][0-9]$/;
		//var reEmail = /^(\w)+\@(\w).(\w)$/;
		var validPhone = document.pizzaForm.telephone;
		var validPostal = document.pizzaForm.postalCode;
		var pizzaAmount = document.pizzaForm.pizzaNumber.value
		//var validEmail = document.pizzaForm.email;
		var finalAmount = " ";
		
		if (myForm.firstName.value == "" || myForm.lastName.value == "")
			{
				errMessage += "Please type in your name\n";
			}
			if (myForm.address.value == "")
			{
				errMessage += "Please type in your address\n";
			}
			if (myForm.city.value == "") 
			{
				errMessage += "Please type in your city\n";
			}
			if (myForm.postalCode.value == "")
			{
				errMessage += "Please type in your postal code\n";	
			}
			if (myForm.province.value == "")
			{
				errMessage += "Please select a province\n";
			}
			if (myForm.telephone.value == "")
			{
				errMessage += "Please type in a phone number\n";
			}
			if (myForm.email.value == "")
			{
				errMessage += "Please type in your email\n";
			}

			if (!rePhone.test(validPhone.value))
			{
				errMessage += "Please type in a valid phone number, such as: 519-555-5555\n";
			}
			if (!rePostal.test(validPostal.value.toUpperCase()))
			{
				errMessage += "Please type in a valid postal code, such as: N2N3M8\n";
			}
			/*if (!reEmail.test(vaildEmail.value))
			{
				errMessage += "Please enter a vaild email such as: example@example.com\n";
			}*/
			if (isNaN(myForm.pizzaNumber.value))
			{
				errMessage += "Please enter a valid number of pizzas\n";
			}
			else if (myForm.pizzaNumber.value == 0)
			{
				errMessage += "You must order at least one pizza\n";	
			}
			
			//Check to see the if the Pizza Size has been selected
			 if (!(document.pizzaForm.pizzaSize[0].checked) && 
												!(document.pizzaForm.pizzaSize[1].checked) && 
												!(document.pizzaForm.pizzaSize[2].checked) && 
												!(document.pizzaForm.pizzaSize[3].checked))
			 {
				 errMessage += "You must select a pizza size\n";
			 }
			 
			 
			 //calculate order
			 if (!(errMessage) && (document.pizzaForm.pizzaSize[0].checked))
			 {
				 finalAmount += pizzaAmount * 5;
			 }
			 else if (document.pizzaForm.pizzaSize[1].checked)
			 {
				 finalAmount += pizzaAmount * 10;
			 }
			 else if (document.pizzaForm.pizzaSize[2].checked)
			 {
				 finalAmount += pizzaAmount * 15;
			 }
			 else if (document.pizzaForm.pizzaSize[3].checked)
			 {
				 finalAmount += pizzaAmount * 20
			 }
			 
			
			if (errMessage != "")
			{
				alert(errMessage);
			}
									
	}
	
	
	//check to see if more then 5 toppings are selected
	function checkTopping()
	{
		var boxCheck = 0;
		for (var i=1;i<=11;i++)
		{
			boxName = "topping" + i;
			var toppingAmount = boxCheck * 0.75;
			if (document.pizzaForm[boxName].checked)
			{
				boxCheck++;
			}
			
		}
		if (boxCheck == 0)
		{
			alert( "you must select at least one topping");
		}
		else if (boxCheck > 5)
		{
			alert( "You can only select a maximum of 5 toppings");
			return false;	
		}
		alert ("Total cost for topping will be: $" + toppingAmount);
	}
	
	
	//To call all functions togther
	function allFunctions()
	{
		checkTopping();
		checkName();
	}

I want to finalize the validation so that once all fields are validated i can show an alert of how much the total cost of the order will be. I want to use the variable toppingAmount that is in the checkTopping function in my checkName function so I can use it and show an alert to show the total cost of the order. I tried to place it outside of all functions to make it global but that is not working. Could you please help me?

Thanks
