Text field combined with price?

Hello!





I want to add a text field on a product where the customer will put a number. The price of the product will be increased regarding this number!



For example…



I want to sell an xbox for 100$. I also give the oportunity to the customer to choose how many joysticks he needs for 3$ per joystick.



So if the customer needs 2 joysticks… he will write the number 2 in the text box and the final price will be 100$+2x3$=106$





Is this possible? How do I implement it?



Thanx in advance!

You could limit the number of joysticks and make a select box with options like:


of joysticks:

1

2

3

4

5

6

7

8

Ok let me give you a hint…



Let’s say that I want to sell a t-shirt, and I want to ask how many text-lines needs in the t-shirt.





I have to make over 50 choises in drop down menu?



Can I do the other thing?



To have a text-box and the number is in there to be added in the final price?





If I cannot do things like those… why the text field exists?

text fields exist for text… i.e. I have a site that sells custom made saddles, and he uses text fields to ask for “Rider Height” and “Rider Inseam Length” you are trying to create a dynamic number of text fields based upon their selection, which isn’t what it’s designed for.

Yeah I know what you mean…





I just don’t want to believe that I 'm so unlucky…





Thanx for your response.
