Populate fields based on Drop Down List Selection
I'm trying to set up a form so that four text fields will populate with data from a previously user entered field (separate text in each text field) at the same time.
Below is a screenshot of the fields that I am looking to populate when "Sole-Trader" is selected from the "employment_type1" dropdown list:

When the dropdown list is set to "Sole-Trader", the data for fields "undefined_68, 70, 72 & 74" is to come from the following fields, which have been completed earlier in the document.

I have reviewed the existing threads and can find the following script, which I have attempted to modify, but to no avail:
var v1 = this.getField("employment_type1").valueAsString;
if (v1=="Sole-Trader") undefined_66 = ("residential_address_1");
else event.value = "";
Any guidance would be greatly appreciated.
