Adding values of list boxes

[geord1e_boy]

Is there anyone out there that knows some php code to enable me to give values to multiple drop down boxes and add these together with a submit button to refresh the page??

For example selecting components for a PC with drop down boxes and giving each component a price. When the user hits a submit button the page is refreshed with a new overall total

thanx

Its a simple case of using a muliple select box, I think the problem U were facing is with respect to the variable used
echo "<select name=\"$list_items[]\" multiple ......

Use an array name instead of the normal when this gets posted to the target page U can just parse through the array as the array will contain the values of the selected elements.
Add these up and show the result.
Hope this helps
