I have one last question. For a multiprice event, can I set multiple (negative) values for the Custom Field extra charge? Something like this:

-10||-20||-30

Your bugfix worked perfectly! Not only is the value in the hidden field now (I can see your switch statement needed those extra lines), but I can see the price change including that discount with the #_DYNAMICPRICE placeholder. (Just discovered that, very cool!)

This is a great first step for me to learn more things about EME. However, of course what I actually need is quite a bit more complex and will obviously need to use a code-type Discount.

The functionality I need to create sounds simple but is probably complex to create by hand:

Members are allowed to get 1 free ticket for certain events.

Luckily, the logic works out that Members should always get the most expensive tickets. Please let me know if what I need is impossible. I imagine it is possible with the right PHP. I think I know just enough PHP to get it done correctly. Wish me luck!

Here’s what my non-member and member blocks look like. Hopefully it helps someone else set up complex conditionals like this! The different #_FIELD{n} placeholders refer to my Custom Fields each of which has a negative extra charge matching the price of the seats in question.

Also note that non-members see a couple levels of tickets at a time if there are only 4 or less seats available in the previous price. I used nested conditionals, since EME cannot do multiple conditions in one [eme_if] tag, nor can it do else statements.
