Require three responses on a Multiple Response item

[I][edited from support email][/I]
I want to require participants to select all three items on a Multiple Response item before they are able to move on. Can you tell me how to accomplish this? I've been poking around in the manual but have not been able to locate one that does the trick...

Try adding a range parameter to your mr question. [I]r3-3[/I] will indicate a minimum of 3 and maximum of 3 responses having to be chosen. So your params might look like this: [I](p3,r3-3)[/I]

Let me know if that helps,
Blair

[quote] Works perfectly. Thanks very much!! It's really cute how if I check one response and try to continue, it says 'But you haven't checked enough items yet!'. <grin> Thanks again.[/quote]
