Thanks but I had tried that too with no success.
Tried again now and the Integer field is not updating its value upon Option selection of the user...
Again, when I set the Integer field value manually in Profile Edit, then the discount is calculated properly and shown on the invoive before the user pays.


EDIT: For unknown reason, I checked again now and it works! I don't know why it wasn't working before. I always clean browser cache...

Case closed, thanks for your help!

EDIT2: I had to pay more attention before concluding it is working, sorry. The int field doesn't update, for sure

Steps followed

-Updated everything to the latest version
-Tried omitting underscore USERLICENSES_P -> USERLICENSESP
-Verified that substitution is not wrong, checked Option Name and even with copy/paste
-Verified that it doesn't push value upon selection (what I expect) but only upon renewal or upgrade completed.

So my conclusion is that Integration->CB Fields works fine BUT the value is not pushed before renewal or upgrade completion.
The latter is what I expect since the user needs to know the price before the transaction.

In my previous post www.joomlapolis.com/forum/255-developer-members-support/245045-limit-shared-subscriptions-based-on-user-choice?start=12#329994 I said it works when I set the value manually. This happens because after I set the value of the int field in edit profile, I click "update" so the new value is kept. Then I click to renew or upgrade my subscription and the discount is calculated correctly.

It is a bit more complicated than this as I am trying to avoid too much overhead.

The code field holds 3 diff variables for the 3 diff plan types.
$licenses_p with discount options updates based on int field cb_lic_qty_p
$licenses_c1 with 20 discount options updates based on int field cb_lic_qty_c1
$licenses_c2 with more than 50 discount options updates based on int field cb_lic_qty_c2
The int fields are shown based on conditionals and all are connected in one code field.
Now this code field is passing its value to the promotion.
The issue is that if the int field is not updated the discount passed to the invoice will be based on the last kept value of the int field.
Using substitution in the promotion and combine all the above would be almost impossible.

Why do you need it to update the licenses field before subscribing?

Because the user must pay the correct amount based on Options that calculates price based on the amount of licenses chosen by the user
Option1 -> 2 -> +100%
Option2 -> 3 -> +200% and so on

Then based on the above I need somehow to calculate the right discount.

So there is no way to somehow update the int field upon option selection, right?
