	# Determine the trial count.
	# The built-in counter 'count_trial_sequence'
	# starts counting at zero (in line with the zero-based
	# indexing generally used in Python).

	# Therefore, we want to add '1' to the
	# counter variable you want to show to
	# the participant.

	# Firstly, we 'get' the in-the-GUI-defined variable
	# 'count_trial_sequence' to use it in an inline_script.

	# To do so, we use the built-in experiment function
	# self.get(). This function takes one argument, namely the
	# name of the OpenSesame variable:
	# For more info, see:
	# http://osdoc.cogsci.nl/python-inline-code/experiment-functions/#experiment.get

	trial_count = self.get("count_trial_sequence")

	# Next, we add '1' to the trial_count:
	trial_count = trial_count + 1

	# To determine how many trials the participant still
	# has to do, we use the previously-defined
	# variable 'total', which we 'get' with self.get():
	trials_remaining = self.get("total") - trial_count

	# Finally, we have to set the here-defined variables to
	# make them available in the GUI:
	exp.set("trial_count", trial_count)
	exp.set("trials_remaining", trials_remaining)

	# To make an in-an-inline_script-item-defined variable
	# available in the GUI (e.g., in our case, a sketchpad item)
	# as well, we 'set' the variable by using the built-in
	# experiment function exp.set().

	# This function takes two arguments: the name
	# of the variable and its value.
