Calculation in PHP page

[shamilwebdev]

 

I am developing php page, I am struck on one part :banghead: 

 

I have 3 dropdown menus.

 

1) Room Type

2) No of Person

3) Extra Person

and a Textbox

 

Now my Issue is, When I select Room type as Executive the amount should be shown on textbox and select "premium" relevant amount should be shown.

when I add Extra Person, Rs 500 should be added in textbox.

 

Thanks

I dont think this a PHP problem to solve. You'll want to use javascript for this.
