Hello!

How would I create a checkbox that:

If clicked once, shows "checked"

If clicked twice, shows "strike through"

If clicked three times, shows blank

Please send over any tips, thanks!

Here's a simple script for creating a 3-state button. Put it in the "MouseUp" action on the button. The font for the button needs to be set to a plain type 1 font, like Helvetica. The the button option to Label Only.

You could also change the border and background properties with each click.

var strDash = "\u2014";
var strCheck = "\u2713";
var strVal = event.target.buttonGetCaption();
switch(strVal)
{
	case "":
	   event.target.buttonSetCaption(strCheck);
	   break;
	case strCheck:
	   event.target.buttonSetCaption(strDash);
	   break;
	case strDash:
	default:
	   event.target.buttonSetCaption("");
	   break;
}

hi, can this be adjusted to have 4 states?

Absolutely, just add another case statement.

var strDash = "\u2014";
var str4thState = "4";
var strVal = event.target.buttonGetCaption();
switch(strVal)
{
	case "":
	   event.target.buttonSetCaption(strCheck);
	   break;
	case strCheck:
	   event.target.buttonSetCaption(strDash);
	   break;
	case strDash:
	   event.target.buttonSetCaption(str4thState);
	   break;
	case str4thState:
	default:
	   event.target.buttonSetCaption("");
	   break;
}

Using the browser you will only see a blank page with a white button with a green check, you must find the "Download" button and open it with Acrobat Pro.
