Making a form field visible when a dropdown select is of a certain value

I put a select field in a form with text values as choices in the table with one of the choices being “Other”.
I have another field which I’d like to have appear when a user selects “Other” in the select field.
I tried a dynamic attribute of show to the value of the select field. That doesn’t seem to work for me. Is that the right way to do this?


I’ll show you the code when using two select elements.

This dmx-show part is created by going to Dynamic Attributes.

thank you . That worked beautifully!
