Populating Text Field with Multiple Dropdown Selections

Question

Hello,

I have a dropdown (Reasons) with multiple selections (Test1, Test2, Test3). I want to be able to select one option (Test1), have that value populate a text field (ReasonsList), return to a new line or have a comma, and then populate another value when I select another option (selecting Test2 after Test1 would give me "Test1, Test2" in the text field).

Is this possible? I've found some Javascript in other community posts, but I'm not able to get it to work for my case.

There is an error in last line: else reasonsListField.value+=", " + event.value;

As the custom Validation script of the drop-down enter the following code:

if (event.value) {
	var reasonsListField = this.getField("ReasonsList");
	if (reasonsListField.valueAsString=="") reasonsListField.value = event.value;
	else reasonsListField.value+=", " + event.value;
}

Make sure to tick the option to commit the selected value of the drop-down automatically if you want the text field's value to update as soon as you make a selection. Otherwise it will only work when you exit the drop-down field.
