'New' and 'Old' price wrong way round??

Can anyone explain this? I have a discounted products, which I've reduced by 20%. Everything looks ok in the Admin section, but actually on the site the prices are reversed...Old price was £7.99, new price £6.39.. screen shot showing problem attached.

Well, are you sure that "eveything" looks right in the admin? Because everything looks reversed on the page. A negative percentage reduction (that would actually be an increase), which comes out to a new price being what is shown... When making the purchase, what value(s) carry through?

Does the same thing "happen" when temporarily using the default template?

How did you effect this price change - using Specials (admin->catalog->Specials)? If so, the number that should be in the Special Price box should be "20%" not "-20%".

When you click add to cart... the value is £6.39

Yes, everything is correct in Admin... 20% reduction, not -20% ... Admin shows £7.99 crossed out and £6.39 as new price.

So would seem template related, how does it look in the standard ZC template when temporarily switched to it?

Basically all of the math and variable assignment is opposite of what is expected... Hence the negative percentage and reversal of new and old prices...

which php script deals with this?

Just to confirm.. this error also happens on the default template.

Indication that core code is modified versus some form of an override.

So, working backwards using the default template code:
In includes/templates/template_default/templates/tpl_product_info_display.php

There is a bof Product Price block.

In there one time charges are calculated (Don't see any in your example, so not a factor), then the affect of attributes where the product is to be shown starting at a value which appends the TEXT_BASE_PRICE text, and then the "power house" or most likely the result that you are seeing comes from the function zen_get_products_display_price... This function is located in:
includes/functions/functions_prices.php

It is more than likely something in this function/file that has been modified, or the above template_default/templates/tpl_product_info_display.php file was modified instead of copying it over to the template override. I say this because the same issue exists in both the default template as well as the templated template... But only you can identify if there is a tpl_product_info_display.php file in the directory includes/templates/YOUR_TEMPLATE/templates/

If there is such a file and it seems that the includes/functions/functions_prices.php file hasn't been modified, then would also validate that the template_default version matches a true default version...

Okay so the above is not in any one specific order and are things that I would check into at some point. If all of this is too much, you could help us (those assisting) out by identifying what plugins are installed or other custom modifications have been performed as perhaps one or more of them affect that file.

Thank you. The problem was in includes/functions/functions_prices.php where the setup HTML if/else statements are. I've now changed it to make more sense and it works as it should.

I think this is twice recently that I've seen something like that... It is important to identify how/why that got reversed and let the "author" know so that less others will be affected...
