Hi cogexp,

your title is somewhat confusing. Would be better 'Var of session_nr" ?
There is a fixed subject_nr within the experiment which is always logged.
If you want the session_nr to be logged you may use this inline_script i wrote for one of my own experiments:

#Session number
session=canvas()
path = pool['session_nr.tif']
session.image(path)
session.show()
nb=keyboard(keylist=[1,2,3,4,5,6])
key, time=nb.get_key()
var.session_nr=key

sessionRP=canvas()
path = pool['session_nrRP.tif']
sessionRP.image(path)
sessionRP.show()
RP=keyboard(keylist=['x','n'])
key, time=RP.get_key()
if key =='x':  # MP left
    session.show()
    key, time=nb.get_key()
    var.session_nr=key

log.write_vars()

As you can see i had 6 sessions. I also asked participants if they pressed the correct number, just in case.
My pictures are in German, but you may easily write some own text in PPT and save it as .tif
[Anyway the forum does not allow me to attached .tif files.]
