Adding Checkbox Values

I am trying to create a 'build a quote' page in which a user can checkoff checkboxes and have the total add up once the submit button is clicked. An example of the code I am using is

<form action="add.asp" method="POST">
option 1 value is 5<input name=""check"" type="checkbox" value="5"><br>
option 2 value is 9<input name=""check"" type="checkbox" value="9"><br>
option 3 value is 1<input name=""check"" type="checkbox" value="1"><br>
option 4 value is 2<input name=""check"" type="checkbox" value="2"><BR><BR>
<input name=""Submit"" type="submit"> <input type="reset" value="Reset">
</form>
<hr>
<%
arrB = Request.Form("check")
arrA = split(Request.Form("check"), ", ")
If arrB<>"" then
For each x in arrA
total = x
next
response.write(total)
end if
%>
