Need help with creating histogram. Error message: Input range contains non-numeric data.

@MrShorty Well, the picture has 243 values for both columns.

I was given these instructions: Casey wants a chart representing the distribution of average hours per week that members utilized Inception Workspace in 2024. Switch to the Average Usage 2024 worksheet. Select the range A4:B243 and create a Histogram chart. (Hint: Use the Name box to select the range.) Modify the chart as described below:
a. Resize and reposition the chart so that the upper-left corner is located within cell D4 and the lower-right corner is located within cell K18.
b. Enter Average Weekly Usage (in Hours) in 2024 as the title of the chart.
c. Modify the bins used in the chart by setting the Bin Width axis option to 10.


The histogram should like look the picture I attached.
