Need to calculate total cost

Hi everyone,

I am not a programmer!!! I need help and have searched the net for an answer. I was hoping that someone could help me out with some coding in Javascript.

I have a form: http://www.digitalimagesbypablo.com/wedding_contract_info1.htm

I would like the customer to be able to see their total cost by selecting the additional services and products the want added.

Basically, I start at a base of $750 and everything they select will be added to the base ($750) to give them a total. However, each time they add something, I would like the total cost to reflect what they choose each time. This way the customer can see what the total cost would be each time they add a product or service.

I provided a link to the webpage so you would have an idea as to what I'm trying to accomplish.

I am in Survival mode because of the economy and any and all help would be highly and greatly appreciated.

 

If you are not a programmer I think it will be very difficult to help you by writing here!! If you allow me to access the code I will do that!!

 

Below is part of the top part of the form code Form code:

The coding for the form was done with my hosts 'Form Builder'. However, it doesn't give me anyway to calculate the 'Total Cost' when they select a product or additional services.

I hope that helps.

 

An example: $750 (start base) + additional time cost (if any is chosen) + additional product cost (if any is chosen) + additional photographer cost (if any is chosen) = Total Cost
