Controlling the Show Variables setting to display either a variable placeholder or the full variable string in a text element

Steps to set a button to show a Pop Up panel as well as include the text string saved to a variable as part of the feedback text on the Pop Up panel.

A Pop Up panel gets shown as a modal window above the main page, which will be shown as grayed-out while the panel is open.

Steps to set a button element to show a Pop Up and display a variable string as feedback.

Let's say I have a variable named stringA and another named stringB. I would like to combine them into a third variable named stringC, but separate by a comma.
Example:
stringA = Pleasantville
stringB = New York
stringC = stringA, stringB aka Pleasantville, New York
How might I go about this? I can't seem to use the Set Variable option, because the Value box won't let me put more than one variable in it. Short of potentially using custom JS, is there a way to do this in dominKnow?

As you create a Project, you’re adding in all kinds of information like the Project’s name, the names of Pages it contains, or what the passing score is for a test.

A lot of that information is available as a System Variable that you can display in a text element.

This example shows how to set a text element to display the System Variable for the name of the Project.

These same steps apply to any of the other available System Variables.

You can display the value of variables in any text element

I have a set of variables like var1, var2, var3.
When all variables have a value of 1, I want o set variable part1 to 1 or any other value.
I know that I could use a trigger everytime var# changes to 1 and check a condition if the other 2 vars are 1, then set part1 to 1, but it's not very efficient and gets messy if we add more variables to track.
Is there a way to constantly monitor the values of var1, var2 and var3 and when all are 1, set the new variable?
Thank you!
