Experiment worked in OpenSesame 2.9.7 does not work in 3.1 version

Psychexppp

I have two possible choice to fix this problem.

One is to downgrade to old version( As my machine is based on ubuntu, it seems does not allow me to downgrade)

If someone know how to downgrade it, please let me know.

Second is to modify my code.

This is error message I got.

If anybody have tip to solve this please let me know.

Stopped
