Sharing my solution, thanks for the challenge.

Hi,

Sharing my solution.

My first attempt to solve this I was going to use binary math:

I had columns set up, 1 for each of the 15 product types, and I was planning to just sum the values of the columns to get a string like : "001001001001001" to represent which products were bought.

Unfortunately I realised that binary math isn't a thing (!!!) and I realised there was an easier way to do this!

Much easier to use the built-ins Tools this way
