The login no longer works. When trying to reset the password, I do not get an email. So looks like the account is not there anymore or is blocked.

On the page you gave: where is the snippet used in question? Is this 'modal-process-buying'? I don't see the issue.
Please make it easy for me to find what I need, instead of making me guess and search through the way-too-many snippets you are using.

In snippet "modal-structure" you are trying to place %url% and %text%. But you did not create any variables for it in the snippet.
Please read the documentation (again) on how the variables work in the Joomla 4 version of Snippets:
docs4.regularlabs.com/snippets/going-fur...ing-dynamic-snippets

No idea what you mean by that... but does it work now?

You still haven't set stuff up correctly.

In snippet 'modal-process-buying' you have:You are referencing the variable %url-process-buying% here, which is empty.
I think you want to include the snippet 'url-process-buying' here. So change it to:
Please double-check your snippets to see if you are using variables and references to other snippets correctly.

Indeed, it looks like you still don't understand it. I'll try to explain it again.

There are 3 different types of tags that are at play here:
- The main {snippet} tags (in your case [%snippet%] tags, as you are not using the default tag characters)
- The %variable% tags
- The [[snippet:...]] Dynamic tags

The main {snippet} tags
This will output the content of the given snippet. You can also pass on the values of variables used inside the snippet.

The %variable% tags
If you want to use %variable% tags inside a snippet contents, you have to create these under the Variables tab.
If you pass the value of a variable via the main {snippet} tag (as mentioned above), the snippet will use that value. Otherwise, it will use the default defined under the Variables tab.

The [[snippet:...]] Dynamic tags
These do pretty much the same thing as the main {snippet} tags.
Except, you can ONLY use these inside the contents of a snippet and/or in the default values of the variables.
The advantage of these is also that you can place these inside a normal {snippet} tag inside the snippet content (when nesting snippets).


Having said all that, let's look at your snippet "modal-process-buying":Here you are using the output of snippet "url-process-buying" to pass along to the snippet "modal-structure" as the variable "url".
In this "modal-process-buying" snippet you are NOT using any %variable% tags in the content.
So the Variables tab should be empty.
You should NOT create a variable for 'url-process-buying' in this snippet.

So:
1) Calling [%snippet alias="modal-process-buying"%] (not passing along any variables).
2) Snippet "modal-process-buying" calls [%snippet alias="modal-structure" ...%], it passes along values for variables "url", "icon" and "text". It uses the output of snippet "url-process-buying" for variable "url". (It does not use any variables itself.)
3) Snippet "modal-structure" uses 3 variables internally: "url", "icon" and "text". So these are defined under the Variables tab, and used in the contents of the snippet via %url%, %icon% and %text%.

What result are you getting?

This doesn't look right:Should probably be:

You haven't created any variables in the snippet 'popup-structure'.
Please read the documentation on variables:

Some of the reasons to have the variables tab in which you need to specifically tell the snippet which variables it can use are these:

- There are no longer potential conflicts with other extensions you might want use inside the snippet that use the same plugin tag syntax as the variables.
- Also no longer conflicts with other texts that contain content that could mistakenly be interpreted as snippet variables (like math based content, like formulas).
- The editor button now knows which variables there can be and which in needs to pre-fill in the tag (if you select that in the snippet).
- It is much more clear what default values a variable has, using that variables tab.
