GSP not producing any results [SOLVED]

In case anyone else has a similar problem, the solution is to use a "Write Text" operator for the pattern instead of wiring it
directly to output. You can then view the results in the text file using a text editor.

Although apparently this is a common question on this board, I have not been able to find an answer to my particular problem.
I am working with dataset 15 found here: http://ailab.wsu.edu/casas/datasets/index.html (Milan).
I extracted only the beginnings of actions from this dataset in Excel, introduced artificial "customers" by simply
assigning the first x elements the name "1" etc, and then used this process to convert the time into a
numerical value and the chosen action from a string into a binomial value (some names are in German):
for different activities, into this process:
definitely repeating subsequences in the data.
This is the log output assoicated with the second process:
directly to output. You can then view the results in the text file using a text editor.

I then feed the result of this (which contains name (1-6), timestamp (converted to a numerical value, thereby equivalent to row number - 1), and binomial values
