reading data set failed

This is a duplicate post, I have answered your question elsewhere.

Yes will fix duplicated post

Please try to investigate your error.

It seems that the file you are reading has no headings in the first line so the "Read CSV" is interpreting the body of text as the field name, so it does not match the attribute name it is expecting.

Possibly your "Read CSV" should have the "first row as names" off?

Thanks Jacob, I will try to fix issue, Your answer was helpful
