On the power apps course you have an error concerning the split and concat functions

Question

In this section: "Splitting up and combining data" you state the following:

"To change those records into a comma-separated list of data, you can use the Concatfunction. The function allows you to specify a formula to process over a table of data and the result of each record is separated by a string you specify. The reverse of this is also possible with the Split function. You can use the Split function to take a string that is separated by a character, like a comma, and turn it into a table of data"

The truth is, Concat will concatenate severals strings separated by command into one value, whereas split will do the oposite. You have it the other way around on your text
