My bot was working before but errors out now

I’ve created a bot and have tested almost every step along the way of creating the automation bot I’ve been needing. I was able to run through at least to the end of my bot but now I cant even start it because my initial datatable now shows that it’s not declared. i haven’t even changed anything about the variable. I didn’t reassign anything either.
Please let me know if you have any ideas.

HI @dhuang

Check the arguments are having anything same variable name
and delete the variable name in the properties and re assign there
