Link to question: https://www.codecademy.com/paths/data-science/tracks/data-processing-pandas/modules/dspath-agg-pandas/projects/pandas-shoefly-ab-test

I am trying to solve this part by using the following lambda function:

`clicks_pivot['percent_clicked'] = clicks_pivot.apply(lambda row: row['True'] / (row['False'] + row['True']), index=1)`

But it is not working and I can’t see why it won’t work!

Could anyone help me ?

Thanks in advance
