Setting up price attributes

Hi, Can anyone tell me if this is possible, I need to make the price attributes so that people can select a text size by a pull down menu (which I have done and range from 25mm to 200mm) Then in a text input box when someone types a word (I have set it to per letter in attributes) in the box the price is reflected on what size they have choosen from the drop down box. I have done this but when I type in the box and add it to my cart it says £0.00. Also need to have price per letter at the side of letter size in drop down box if possible.
Thanks all.

Have a look at the demo price per letter
**DEMO HERE**

I had a look at the demo but I'm still not 100% on how I can obtain the soloution as in my original post? Doing it the same way as the demo I would need to set a box for each text size in mm then place the price for each letter in its attribute. Shane

You will have to work out how to present these

There is no support for "dependent" attributes in ZenCart

This being "select the size" and it then upscales the per letter cost

yes but if I select 25mm size then each letter should cost 52p each, as this is what I set it to in my attributes each letter costs, am I right in thinking this is how it works? but if I type a word in the text box "no" then when I click on add to cart the total cost of this should be £1.04p, but it says £0.00. Thanks for your time.

I think you are expecting something that I have already stated is not supported
