Thanks for your help
Description of the problem:
I display a series of images via 3 loops
A) the first loop i which will read from the file NumBloc.xls the name of the file of the series. it is my variable $blocnumber
B) the second loop j will read from the file $blocnumber.xls the condition of the experiment $conditionFile
C) And finally the 3rd loop I randomly present the images contained in the file $NumFile.xls via the variable $Filename
the display seems to be done well but In order to debug
I want to display under the stimulus image the variables
$blocnumber
$conditionFile
$Filename
in order to verify that I will look for my stimulus image in the right file according to the conditions i,j
but I get the following error
text=blocnumber,
NameError: name ‘blocnumber’ is not defined
