A newbie's simple question

[welles]

Hi there,

I added two type of unbound fields (string and number) to a blank report and tried to reference the field's name and change their color. But I received the "invalid report object name" error. Can any expert here tell me what I am missing or what I have done wrong? Thanks in advance!
