Adding an item in the middle of a questionnaire?

[I][edited from support email][/I]
I am trying to make a questionnaire, and I came up with a problem- how do you add in an extra cell in the middle of questionnaire? I could not find the solution in the help section. I would appreciate your feedback greatly!

Try giving it a position number with a decimal value--in between the two items where you want it.. like 5.5 to get it between 5 and 6. Then click [I]Sort[/I] and [I]Renum[/I].
