calculating question

just starting out with php...here's my situation:
1)i have 4 text fields in a form and they are in an array

2)array_sum adds the values of the fields and is supposed to display the total as a variable using echo. it does this but the total is always 0. makes sense if all the fileds are null but when i change them, the total is not being refreshed in realtime.

3)i need the total variable to update every time one of the values in the 4 fields changes in realtime, so i get a running total displayed on the page. i don't want to do this clientside with javascript.

can anyone help?
thanks

This can't be done with PHP alone, if you want PHP to do the calculation you're going to need to use AJAX, which requires Javascript to be used.
