Adding a Checkbox and Setting up the Checkbox Variable

Steps to add a Slider and setting up the Slider Variable.

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.

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

I have a course that has a checkmark toggle. When the box is checked, it enables the Next button. In Chrome and Internet Explorer, the checkmark shows when the checkbox is clicked on and the Next button enables. In Edge, the checkmark does not show when the checkbox is checked but the Next button enables. Is there something I need to do so that the checkmark will show?

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?
 

Steps to set a Marker on a Video to increase a Variable.

You can use this when you want to launch an action after an Element(s) within a Video is clicked.

Steps to set an element to increase a Custom Variable by 1 when the learner clicks on the element.

In dominKnow | ONE, you create a Custom Variable as part of setting up the first action that will set its value. (You don't need to create the varibale first then create the action to set its value.)

In this example the action is set to fire only once so if the learner clicks on the element more than once, the variable's value isn't increased after the first time click.

After this first actio...

Having trouble setting up variables to do this:
Image A when clicked shows a pop-up with text (variable show pop-up)-this part I understand. But not this: When the text banner is closed, Image B REPLACES/OVERLAYS image A. How do I do that?

You can use a button to set a Boolean variable to True or False. In this example, we're setting the Variable to True to track that the learner competed the Page by using the Return To Menu button. We can then evaluate the Variable's state on other pages and use it to trigger other events.
