You didn't attach any files, but is your file in the form of a 2D array?  Why can't you just index the second column and then index the third column and multiply by 10?  Are you wiring a 1 into the index (col) of your Index Array?

Cheers,

Clint

Hello... 🙂 it will be more clear if you attach your file... But you can try as Clint said if your file is in form of 2D array or your retrieving data in array format... 🙂

...anyway, you can import your file as text (array of strings), discard the first data of each string with the "string subset" function, and save it back to a temporary file. This temporary file has now your former 2nd column as first, and former 3rd as second.
