I have 4 checkboxes on a page with different values for each, if the user selects any (or all) of the boxes i want a label to display the total amount, i have got the label to display any 1 value but cant add it all up. Any ideas?

Kind of depends upon if you want to use javascript to update the label in place, or if you want to make a trip back to the server. Also depends if the check boxes are part of a group, and all have the same name, or if they each have a different name. If a group, you'd treat them like an array. -------------

| the check boxes are not part of a group. if the user checks checkbox 1 i want the label to disply a value, if the user uncecks the box, clear the value. Also, if the user checks 1 or more, add up all the value (subtracting if the box is unchecked) |

As you're changing the display on the users machine, you'd need to use javascript. There's probably scripts available for doing something like this on the scripting sites.
