Difficulty with pdf form trying to "choose" one of two paragraphs of text

Question

I am creating a PDF form and trying to find a way to choose one of two groups of text that are about paragraph long. and only having the the one I choose be visible on my pdf.  I tried using a dropdown list, but it would not accmodate the amount of text I needed

Answer 1

OK, the following is for a single check box and a single field. If the check box is checked the multiline text field will display one block of text, and if unchecked, it will display the other.
I'm goping to assume the text field is named "Text1". The Mouse Up JavaScript of the check box could then be:
// Get a reference to the text field
var f = getField("Text1");
// Set the value of the text field depending
// on the state of this check box
if (event.target.value === "Off") {
    f.value = "Paragraph 1 goes here. You can use \rto indicate a carriage return.";
} else {
    f.value = "Paragraph 2 goes here. Add as much text as you like...";
Change "Text1" in the getField statement to match the name of your multiline text field.
