Is there a way once this script is set up to allow the user to overwrite that field with a custom entry? This works EXCELLENT but there are a few cases in my process where a custom entry into that field would still be necessary at times but it seems that every time I try to enter something in it is just overwritten by the script again. Thanks for any help you might have!

Add this line of code before the current one:

if (event.source && event.source.name=="dropdown")

Excellent!!! You just made my day. Thanks! I'm not very good at code at all (meaning I have no idea what I'm doing ever) but this worked great. Thanks a lot!

Put these letters as the export values of the items in the drop-down, and then use this code as the custom calculation script of the text field:

event.value = this.getField("dropdown").valueAsString;
