How to go back to to Custom Column Formula from the Add Conditional Column window?

[justlogmein]

If I type in a simple if statement into a custom column formula window and press ok, sometimes it will then default to the Add Conditional Column window when I re-open it. I want to add some conditions to my forumla and I can't go back to typing in custom text. Does anyone know how I return to the original window?

@ImkeF -- any idea why this works?

[ImkeF]

The _ will return a record, which cannot be displayed in the structured editor.
the quotes around the column references make it a text field and the structured editor is only supposed to have a proper column reference as the first argument.

You can either replace the null by _ or put one column refrences in quotes "[Response]": that will bring back the old editor where you can revert these changes and continue editing.
