Tax Value Problem
I am new to web design and I am having a problem with tax rules.
The cart has to calculate the tax value, but since it is already included on the price item, I need the cart to state the figures as follows:
The catalogue shows: 115.00 and the cart must show this as follows:-
Sub Total £100.00
Tax £ 15.00
Total Incl Tax £115.00
I have tried adding the following rule to my cart object as previously mentioned in another successful solution.
([Price] - ([Price] * $_SESSION['tax'])) * [Quantity]
but i keep getting the error
Notice: Undefined index: Tax in d:\wamp\www\AB\WA_eCart\AngelBeeStore_PHP.php on line 368
I have included copies of the ecart images and a copy of the relevant AngelBeeStore_PHP.php code
I would appreciate any help with this matter.
