Javascript popup if checkbox is checked using radio button

[samueljaybrown]

I am looking for a javascript to cause a popup info box IF a checkbox from a radio button is selected.

I have a section PDF form that involves how an employee was transported to get medical care. They are given 3 options.

There are 3 radio buttons that correspond with this section

The first one is ambulance,

second is personal auto,

third is employee transported.

If the person filling this form selects the ambulance option, I want a box to pop up that states "You must contact HR Department @ ###-###-#### immediately"

The box should have an option to click "OK" and an "X" button to close the window. Please help! 

I do not want the javascript to happen if the other two options are selected, only the "ambulance" option.

Thank you

Here is an article on the topic, and it even has a sample file linked at the bottom

You can use this code as the Mouse Up script of your radio-button fields:

if (event.target.value=="ambulance") app.alert("You must contact HR Department @ ###-###-#### immediately",3);

There's no "X" button to close the dialog, though, just an OK button.
