Error run script but smothly in builder

Hi, OS team
I am new in Psychopy and just bought a very good and easy understand book Psychopy from Jonathan Peirce. For beginning I make Stroop task with builder and everything just fine, run smoothly. However when I am trying use coder for running Stroop task (that emerge from psychopy coder) it always return to error. “AtributeError: Ordered dict has no attribute word”. Suppose from line “exec(paramName + ‘= thisTrial.’ + paramName)”. I run the script coder using Window Terminal. As long as I understand error might comes from dict word in excel file. Until today I will stick to the builder as I see very stable and easy to understand.
Many thanks for the help.
