Trying to figure out a few things Help please

Alright, I know how to link a journal to a click-able link but I am trying to create a click-able link to output text directly into the roll20 chat. I haven't been able to get any command to work that I know of thus far.

Second, I am using a random table for a quest where they drink from a fountain of gods and random things happen. I am unable to get a rolled result in the text from a random table.
Example: Drinking the water results in a fort save DC 15, or take [[10d10]] acid damage.

The bracket text needs to output a number but does not. Is there a way to make that happen.

The Roll20 chat uses a cut down version of markdown syntax. The syntax for a link in chat is [Text to Display](URL). This is also the syntax that the command buttons are based on.

For you question about the rollable tables; this is only possible via the API (Pro perk), specifically Aaron's Recursive Tables script.

What is the URL to the text chat

Ah, are you trying to make a journal command button that you can click to output something to chat? Then that is a little different:

From the wiki on journal command buttons:

Here's how to create a Journal Command Button within one of the aforementioned fields:

1. Insert a link using the link button on the redactor toolbar.
2. At the very start of the "URL" field of the Link Window, type !
3. Add in your macro code after the !
4. Give your Journal Command Button a label using the "Text" field.
5. Press the "Insert" button and Save Changes; you have created a Journal Command Button!

Keep in mind, journal command buttons don't work if you have the journal entry popped out into its own window.

Alright so this is how I am guessing it works


! (/desc BLAH BLAH BLAH)

Would be:

!
/desk BLAH BLAH BLAH

Look at the linked page, it's clearer. The forum eats HTML entities, so they got stripped from scotts message. 

Thanks
