Tutorial - error in bar chart code

[dkt_idusa]

I am a new user and was trying to go through the tutorial. When I got to the part that allowed me to create a bar chart using the data provided, I get an error message within the coding, even though I am using the chart wizard. Does anyone know if this is a known problem with the tutorial or if it is just on my end?
