Also, I want to get the software to take the values from this table, when called and use it in a equation as in excel. Thanks in advance

Prime is complaining because it cannot have a value "NA" with units, like % or pcf. (Note that you do not get an error for the column labeled e that also contains "NA"s.)

If you change all occurrences of "NA" to NaN (without quotes ! ) it should work.

NaN is a special symbol that means "not a number".

Once you've gotten rid of the errors, you can calculate with your variables. Note that every column of the table is in effect a vector.

You could for example calculate LL+PL, and get a vector with values (35 35 57 87).

Success!

    vector by default are numbered with indices beginning at 0. You can change this via the system variable ORIGIN.

    So to add the first values of a and b you would type a[0+b[0

    The "[" is the shorcut for the matrix index. You can also get it via the menu.
