Multiple drop down menu items to populate the same separate text box. How can I do it?

Question

In Acrobat Pro X, I've figured out how to create a drop down menu with items that will populate a separate text box, but how can I get multiple menu items to populate the same text box. For example. My drop down menu has three items  cat, dog, mouse. I choose cat and it appears in my separate text box (hooray). Next, I choose 'dog' from the same menu. I would like it to appear in the same text box along with my previous selection 'cat.' Is this possible? I'm very new to Java Script, any assistance would be greatly appreciated! Thank you

She is the script I'm using
(function () {
    // Do nothing if not committed
    if (event.willCommit) return;
    // Set up an array to hold the individual paragraphs of text
    var aQuotes = [3];
    // Populate the array with the paragraph text
    aQuotes[0] = "cat"
    aQuotes[1] = "dog"
    aQuotes[2] = "mouse"
    // Get the selected item, which is the export value of the selected combo box item
    var item = event.changeEx
    // Display the text corresponding to the selected item in the text field
    getField("Text field 1").value = aQuotes[item];
