Hello friend,
I hope I will be able to help because I’ve gotten so much support from this forum. I’ll try my best to explain what I did.
To begin, here is my database:

Now in it, I have similar things to you. My item name, unit of measure for the item, quantity. But I believe where my database probably differs from yours is that I combined all those into a strong WITHIN my database:

So you can see my data base will contain something like: “2 box(es) of paper within 1 wk”
This will all be recorded within the string column.
From there you can see that I use the join with function in my send email workflow:

Notice that it only will appear after you do a search for the database item you wish to include. Also, I believe you will have to manually enter the “line_break” function.
Hope this helps!
