When i use xlsread command, i get this error "index out of bounds because size(data)=[33,5]."

The xlsread command used to work fine for me until this happened. Below is the code i'm using: clc clear data = xlsread('Crss_measured.xlsx'); x1 = data(:,1) x2 = data(:,2) x5 = data(:,7) x6 = data(:,8) semilogy(x1,x2,x5,x6) axis([0 600 0.0001 10000])

And the error i keep getting which i don't believe is the error:

Attempted to access data(:,7); index out of bounds because size(data)=[33,5].

Error in Crss_excelread (line 9)

Plz help! x5 = data(:,7)
