Unable to reset parameter

Hi, I’v just installed SuperLab 5 and I get the following message when I create a new experimet. The experimet is a very simple test with one block, one trial and two events. “Unable to reset parameter [No Parameter]” this happens on both the PC and Mac versions. Am I missing something simple?

It’s hard to tell without seeing the experiment, but a best guess is that you probably checked a checkbox for some feedback option on one of the events.

If this guess is not correct, then please post the experiment and I’ll take a look at it.

My fault, I had indeed selected a check box and never noticed it!! Thanks for your help.
