$NaN value in pavlovia even if PsychoPy references source Excel correctly

@fmtoma

If I specify Math.round(variable,0) - for example Math.round(loss,0), I get NaN.

This is your issue. In Pavlovia you can’t edit spreadsheet variables. Try

loss2 = round(loss,2)

and then use loss2 in your msg.

Variables set by spreadsheets should not be set or edited in your code. If you need to change the value, copy it to a new variable and edit that.
