Hello

I hope I can get some ideas here!

I created a form for booking a different services, and all these services has many features. So I want to select a feature, and its cost automatically to be added at the total cost(which should be displayed and updated on the same page), via drop-down menu selection.

I know that in order the values from the form to be processed, I have to submit the form, but is it possible only with php, by clicking on an option in the dropdown menu the total sum to be shown on the same page each time feature is selected.

Cheers in advance!
