I just tried checking out with the Apply Discounts After Taxes option and nothing changes. I think this option may be broken?

Taxes are indeed calculated before summing products prices as it is common practice in Europe AFAIK and that it is more logical for users ( some customers will refrain from buying because if they buy 5 items at €5 and they are charged €25.02 they will think that your website is not serious enough ).

If you want to calculate that differently, you can build a product quantity calculation override plugin using the explanation there:
[ www.hikashop.com/en/support/documentatio...tation.html#override](http://www.hikashop.com/en/support/documentation/62-hikashop-developer-documentation.html#override)

For the Apply Discounts After Taxes option, I recall that there was indeed a problem with previous versions of HikaShop. Do you have the latest version ?

I should be, I'm running 1.5.3.

I'm not terribly qualified to create my own override plugin. If it's just a matter of copying a file and changing a line or two of code, then I could handle it, but from the description you linked it seems like quite a bit of work. Do you know of anyone who has already done this that can provide a file for me to download?

No one has done such plugin yet.

I've made a plugin for you for that but it's not tested so it might not work. Let me know if you get errors.

Thanks so much! I dropped these files into plugins/hikashop, then navigated on the Joomla back end to Hikashop &gt; System &gt; Configuration &gt; Plugins and it wasn't there. I also tried checking out and it doesn't seem to be implemented. Did I install incorrectly?

Thanks again.

You need to install that plugin via the joomla installer.

I tried that as well, but I figured it was the wrong thing to do because I got this error:

Indeed, the xml was not correct. Here is a new package with the xml file corrected.

Great! That installed correctly, but now no taxes are being charged. Can I move this issue to email? I believe I still have the address.

An error on install:

JInstaller::install: There is already a folder called '/xxx/xxx/xxx.com/plugins/system/custom_quantity_tax.php'. Please initially check whether:
• the Extension is already installed
• the file names in the XML file are spelled correctly
• there are no XML files listed inside the extension.xml file
• all of the files (not including XML files) are correctly listed in the extension.xml file and there are no duplicate entries
• there is an empty folder listed from a previous installation attempt

So I unzipped your zip file and replaced the two files in the plugins/system folder, but that didn't work. Is there something else I need to delete before I install this updated version?

You should uninstall the plugin before installing it again. Also, make sure that you don't have the files /xxx/xxx/xxx.com/plugins/system/custom_quantity_tax* before installing it. then, you should not have the error when installing via joomla.

You say that it didn't work. What do you mean by that ?

It said the plugin was already installed, even after I deleted the files. The exact error is:

Plugin Install: Plugin "custom_quantity_tax" Already Exists!

It's because you still have the plugin registered in the database of joomla. You need to uninstall the plugin not just remove the files.

Anyway, here is a version of the plugin which handles the install over an existing version of the plugin without uninstalling the previous version. That should solve that install problem...
