Can someone make the following corrections to my Excel2016 sheet?

I can't figure out how to make a combo chart correctly, I'm not getting the option and that is messing up some of the rest of my steps.

Refer to the instructions page- I only need the combo chart created, that is only the first few steps or less

Select the ranges A4:A10, F4:G10 and create a Clustered Column - Line on Secondary Axis combo chart. For the Data Series '% of Month' in '[November 2018 Downloads by Genre] Custom Combination' Chart, type was not set to 'Line'. For the Data Series '% of Month' in '[November 2018 Downloads by Genre] Custom Combination' Chart, subtype was not set to ' Line'. In the 'Custom Combination chart' on the sheet 'Data', the 'Source' was not set as per the instruction. Position the chart to start in cell A13. Change the height to 3.5 inches and the width to 6 inches. In the 'Custom Combination chart' on the sheet 'Data', the 'Width' was not set to '0.64'. Add a primary value axis title and type Number of Downloads. Add a secondary value axis title and type Percentage of Monthly Downloads. Apply Black, Text 1 font color to both value axis titles.

Move the chart to new sheet Type Bar Chart for the sheet name. In the 'Stacked Bar chart' on the sheet 'Bar Chart', the 'Source' was not set as per the instruction. Use the Axis Options to display the value axis in units of Thousands, set the Major Units to 500, apply the Number format with 1 decimal place for the bar chart. Use the Axis Options to format the category axis so that the category labels are in reverse order in the bar chart. In the 'Bar Chart', 'Stacked Bar', 'Value Axis', the 'Major Unit' was not set to '500'. Change colors and apply Color 12 to the bar chart. In the 'Stacked Bar chart' on the sheet 'Bar Chart', the 'Color' was not set to 'Color 12'.
