Set the drop-down to commit the selected value immediately (under Properties - Options), and then use this code as the custom validation script of the text-field (of course, adjust the name of the field to match yours):
event.value = this.getField("Dropdown1").value;
Thank you for responding. Unfortunately no it doesn't populate the targeted text field. I removed this script from the "Actions" tab of the Drop down box:
var target = this.getField('Textfield');
var cBox = this.getField('dropdown');
target.value = cBox.value;
and used what you gave me and pasted it into the validation script area in the text field. Now nothing is populating the field.
Sorry, it should be the custom calculation script (of the text field, of course), not validation. And remove any other code that you have used to do this task.
Thank you so much for the help. It works like a charm!! Gilad Rocks!
