    @zus: I believe, you set your configurable product(parent) price as $0(or not set) and hence you are getting this result. It is better to set the base price for configurable product based on the simple product which cultivates configurable product and the difference in price (for simple products) in the super attribute section.

The most likely issue is that you are using an extension which is changing how configurable products work or your theme is doing it.

Most extensions regarding configurable products change the functionality to use prices directly from the child products (the products assigned to the configurable product).

I can recommend several things you could try that might help you debug this issue:

  1. Check if you have any javascript errors on the product view page
  2. Check what price you put for the configurable product, if it was created programatically, it might have a null price which could cause problems
  3. Check if the configurable product is in stock
  4. Check if the child products all have a non-zero regular price and that they don't have a special price set to 0
  5. Make sure the child products are all in stock and that they have quantity > 0
  6. Try putting a 0 in the red color option instead of just a blank
  7. If you have an extension that is affecting configurable products, you can try switching it off
  8. Try switching to the default Magento theme and check if it's working then

  • Did you try my other suggestions? The problem might also be that you made some changes to /catalog/product/view.phtml or /catalog/product/view/type/options/configurable.phtml? For example, if you had changed some classes of the price element or some of it's parents, the theme functionality to change the configurable product price might have broke. Also, what happens if you change the color to navy blue? Do you get 95 Rs?

    There is nothing I can say without seeing the contents of the view.phtml and comparing the original with the modified version. My advice is to put back the original view.phtml theme file and check if it works then. If it does, then maybe you can figure out what change has broken the functionality. Maybe it isn't connected to view.phtml, but maybe it's some other part of the theme... I cannot say exactly without looking at the files and/or the shop URL. Good luck to you @zus

    I checked the extension and the error is probably connected with the text "free" which the extension is replacing when price is 0. Most probably, for configurable products there is a functionality which tries to do some numeric calculations. For example 0 + 10 = 10 and with this extension it tries to do "FREE" + 10 = ERROR. If you don't need the "FREE" text for configurable products, then you can adjust the extension funcionality and check if the product is configurable before the extension replaces 0 with "FREE".
