Update/Calculate condition not working

Yesterday I used the update/calculate condition to copy an address  from one address field to another based on a drop down selection, worked fine, then during further testing it stopped working. I have tried every possible combination I can think of without success.

I have now created a new test form from scratch https://form.jotform.co/90813917241860 and still no luck!!

Can you help here

The condition logic is correct and should work.

BUT in the live form, Address 1 is a hidden field... so the users will actually not be able to fill in Address 1 .

Because it is blank/empty, there is no data that can be copied to Address field using the Conditions.

Those placeholder text/hint text are not actual values/data. There is no default data value in the Address 1 field.

A workaround you can do is to use multiple Short Entry fields(Textboxes) that have default value and use them to populate the Address field using Conditions.

Thanks Jonathan, understanding that the placeholder text has no data value is key to my problem, I have previously used the "show" condition with the appropriate address displayed based on the "Client" selection, however in this form with up yo 30 clients which may be used up to 10 times in the form and 16 addresses this method was no longer practical. Your suggestion of multiple pre populated fields should solve the problem.
