X must have length equal to the number of rows in Y, but I'm pretty sure they're the same size

Hey all,
I'm trying to plot something, but I'm getting the error mentioned in the title even though I think everything I'm tying to plot is the same size 1x12).
My code is below; I'm trying to put distance on the X axis and plot the other 3 variables on the Y axis.
Edit: I've also tried it within the (1:12) callouts on the first two variables, same error
Thanks.
salinity = [31 31 33 26 25 22 22 22 22 22 20 21];
distance = [0 206.4 367.2 486.9 616.3 743.3 1141.8 1145.1 1225.3 1232 1232 1232];
nutrients14 = readtable('C:\Users\ejs7c\OneDrive\Desktop\transect14data.xlsx');
nutrients181 = readtable('C:\Users\ejs7c\OneDrive\Desktop\transect181data.xlsx');
nutrients182 = readtable('C:\Users\ejs7c\OneDrive\Desktop\transect182data.xlsx');
nutrients19 = readtable('C:\Users\ejs7c\OneDrive\Desktop\transect19data.xlsx');
pwnutr = readtable('C:\Users\ejs7c\OneDrive\Desktop\pwdata.xlsx');
stackedplot(distance(1:12), salinity(1:12), nutrients14.Var12(101:112), nutrients14.Var12(114:125));

nutrients14 is a table in which case those will be column vectors instead of row vectors and stackedplot needs one X and an array of Y. It puts each column in Y in the plot by sequence.
NB: You don't need subscript expressions for distance, salinity, but you need to group the Y variables into one array --
stackedplot(distance, [salinity.', nutrients14.Var12(101:112), nutrients14.Var12(114:125)]);
