Data structure does not have the same order. Check your variable names and order in your file and data structure. Names need to be identical. (year,subsample)
The variables in your file and in the data structure need to be exactly the same, not only the names need to be same, but also the variables order, which variable is on the first column, which is the second.
You should change your file variables order according to the data structure. Or you can change the data structure variable order.
