Form with Checkboxes and Conditional Text

Question

Hello, I am VERY new to Javascript and have been scouring these threads to find a solution, but I'd appreciate any assistance! I'm trying to develop a conditional form with 8 checkboxes. If a checkbox is selected, I want the applicable text to appear. I was able to make this work using the Actions Tab and "Show/hide a field."

However, if the checkbox is unchecked, I'd like the text to be hidden. I drafted the code for a text field, but that didn't seem to work:

if (event.target.value("CHECKBOX").value=="Off")
event.target.value("TEXTFIELD").value="";

Also are there any suggestions as to how to adjust the formatting if only 4 of 8 checkboxes are applied? I tried to input the terms into a table, but I'm not sure how that would work...

event.target is used if your script is executed directly from the target field; in this case, for example, a checkbox field.

You may modify the script like this:

/* 
first declare your variables, as a good rule of thumb always place your declarations at the very top of your script(s)
*/

var f = event.target;

var field = this.getField("TEXTFIELD");

// then establish your IF condition(s)

if (f.value == "Off") {

text.value = "";

}

As to how to achieve this when at least four out of the eight checkboxes are checked, a more elaborate JavaScript script is needed; it is not that trivial if you're new to Acrobat JavaScript.
