I want to make configurable products with carpets in a way so that the customer can pick the width of the carpet and the length. The width is fixed e.g. 60cm, 80cm, 100cm and 120cm. But the length is supposed to be entered in a text box and multiplied by the price of the width so that the customer can choose whatever measurement.
Example:
Dropdown: 80cm = 12$/m
Text box entry: 2.2m
So the price would be 26.4$
