This public service announcement (PSA) outlines best practices when asking for help. Following these points makes it easier for us to help you and more likely you’ll get a prompt, useful answer. Keywords are highlighted to make it easier to refer to specific points. Choose a descriptive title that captures the key part of your question, eg “plots with multiple axes” instead of …

I am guessing that recent updates to the XLSX package may use a different syntax than the older version used in the tutorial.

The code below will read your Excel table into a DataFrame and then access the first column.

```julia

G = DataFrame(XLSX.readtable("data/zillow_data_download_april2020.xlsx", "Sale_counts_city"))
first_column = G[:, 1]

```
