Hey all i need help with the formula section of this program.

 

So i have a few dropdown menu's all containing text and numbers but what i want to do is when the user selects one of the drop down menu's it add's the price of that item to the total cost and display's it.

So i need to somehow get every little part of each dropdown menu and declare a different value to it and then make it at the end add them all together and then display. I would like it if it updated this total after every change the user makes.

 

Any help would be greatly appreciated as i have no clue with this program.

Many Thanks crackruckles
