[solved] help! "not enough arguments for format string!"
since there is no program for win7 of 64-bit, I have installed opensesame_0.27.4-win32-2. I want to make an experiment for android devices, but there happen to be a problem when I click the loop icon. I could see the codes but not the chart of independent variable. Instead, it pops up an error box indicating "not enough arguments for format string". this also appear when I click the "apply and close" icon in the script dialog of loop. So what is wrong? How could I see the independent variable chart and make some settings? Please help me. Thank you.
