UiPath Studio encounters run time error while executing "repeat with counter loop"

Hi,

I'm doing "Step into RPA" course. As i was practicing the examples shown in the video i encountered this error. I followed everything as per described in the video of using "repeat with counter loop". But it got executed in the video but it showed error in my system. In the video, they were creating a simple Bot to Open Notepad automatically and type the text "REPEAT" 5 times one below another using "Repeat with counter loop" which is actually "do..while" loop in programming terms. When Run, the Notepad is opened and the text "REPEAT" is typed one time alone and the cursor comes to the next line and it shows "run time error" from UiPath Studio.

I've just completed the course and to say the truth the course was good but the examples shown are not working in our systems or tool. It runs in the tool used in the video but in real time it throws some errors. Most of the examples face the issues. Please rectify the course content.
