Problem with my expression and .csv file

Hi everyone,

I want to create a dynamic text that connect to a .csv file.

This is how my .csv looks:

If I use this expression, I can see the value of the first column, row 01. So, that´s fine: 
footage("mylist.csv").dataValue([0,1])

But If I try to see the second value, same raw, using this expression:
footage("mylist.csv").dataValue([1,1])

I get this error.

Can someone help me? Thanks in advance!
