Check Boxes fill out 3rd page

[Chris_N24]

I want to know if there's a way to fill out a separate form depending on what boxes I check on the first 2 forms. Like if I click on check box 1, 3, and 5, then it'll fill out fields in 1a, 1b, 2a, 2b, 3a, and 3b in the last form. Just the same, reverse if the boxes are unclicked. Also, after you unclick them and click on 2 and 3, then it'll fill out 1a, 1b, 2a, 2b, 3a, and 3b. Any help with this issue would be greatly appreciated.

Also, I should mention that the info that goes on the 3rd page won't be the same as the information on the 1st page. For example, I want it to be where if I click on check box 1, then the information that will appear on the 3rd page will be something like Aces, Kings, Queens. Then unclicking box 1 and clicking on check box 2 will fill out Tens, Nines, Eights in place of the Aces, Kings, and Queens. Then if you click on both, then it'll fill out the form with all the above listed in order of when you clicked on them.

If by "form" you mean pages in the same PDF, then yes, this is possible with a script. 

The best approach would be a custom calculation script in a hidden text field. Calculation scripts are run anytime any field on the form is modified. So they are both dangerous and very useful. 

Here are some articles on calculation scripts.

Thank you so much for all of these resources. They've helped out a ton. I've got half of what I was looking for. Now I'm trying to figure out how to apply a way to have several check boxes that fill out a single text box without overwriting each other. I want it to just add it into the text box as a new line (like hitting enter before typing something else in), and if I checked on several then decide to uncheck something, it'll remove that from the text box, and mover everything else up so there's no gap in between each new line.

Use a calculation script in the text field where the text will appear.

For example:

*The checkboxes are named "Grp1.Chk1", "Grp1.Chk2", etc.

*The text values are the export values of the checkboxes.

event.value = "";

var aFlds = this.getField("Grp1").getArray();

for(var i=0;i<aFlds.length;i++)

{

     if(aFlds[i].value != "Off")

         event.value = aFlds[i].value + "\n";

}
