Hlookup & Right
HLOOKUP Per the website, "HLOOKUP stands for Horizontal Lookup and can be used to retrieve information from a table by searching a row for the matching data and outputting from the corresponding column. While VLOOKUP searches for the value in a column, HLOOKUP searches for the value in a row." Below, I wanted to return the number of Basis invoices paid on week 1, week 2, week 3, etc. I used the right formula here because the row index number is always one more than the week. Alternatively, on another sheet, I also just used an array constant that allowed me to use just one single formula to output the same result.
