Hi Dolly - The best solution may be to use the EXE command at the end of the second study. Within your experiment file, input the location of iexplorer.exe after the second study. For example, on my machine iexplorer.exe is located in the following location: C:\Program Files\Internet Explorer\iexplore.exe .

Within the parameters field, add the following command-line arguments: (chttp://www.empirisoft.com/support/ max) - Include the parenthesis. This syntax denotes that we want Internet Explorer to open up Empirisoft's Support page and then maximize the window. If this is the last command on the experiment, MediaLab will finish its tasks up and study 3 will begin.

There shouldn't be any data issues using this method. Nothing from the third study will be saved, as it isn't being run from within MediaLab. Aside from that, test and make sure that the entire ML experiment ends after iexplorer is launched. In order for MediaLab to save all of the data recorded during a session, it needs to reach its last screen and end.

For more information on how to execute ending processes and piggyback external experiments through the .exe feature and command-line arguments, see the following help page:
