I am new to this and I can't find a way if there is any to show a variable in the bot panel when it is running.
I will attach an image for better understanding.
For first error try to check "Also check if visible on screen".
For second error log that variable to see what happens with it.
Basically log everything that might causing that error to be able
to debug script and find error point.
In the future please share sxript that replicates your problem/error.
Othervise I doubt someone will be able to help you.
