Form and List Error

I just added a Look-Up column to my form. I was trying to populate a dropdown with a list of users.

Under Advanced column options I added the following:
Source Column: Link to Profile
Token Text: [User:FirstName]

Now I am getting the following error and cannot get back to the form.

Error

A critical error has occurred.
Object reference not set to an instance of an object.

Is it possible to undo this?

Re: Form and List Error

it doesn't look wrong, did you try to restart application (using command in Host Settings)?

Re: Form and List Error

I just tried that and still receive the same error. The form was working fine before I added that column.
Is there a way to remove it?

Re: Form and List Error

you may delete the column in the database (last item in table UserDefinedFields) and restart the application. to clear the cache.
