Is there a widget with automatic totaling lists?

We are looking for a widget that keeps a running total of the dollar amounts that our customers will be entering into lists.

For example:

How many apples do you have?     4

How many peaches do you have?   3

How many bananas do you have?   1

Your total fruits:                            8

Is there a widget that allows us to do this?

Thanks!

You can use a form calculation widget to total up values in the form:

It is also possible to assign options calculation values and use those values in calculations:
