Access a specific element of a data array?

Hi
This must be a very simple question but I could not find the answer in the Documentation Center.
I am importing data from a file that contains two columns of numbers:

data = Import["myfile.txt"]

How can I access a specific element in the data array, e.g. column 1, row 3?

You can use Part.

E.g.:
data = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
data[[3,1]]
7

Thank you but that does not work. The array ‘data’ must be having a different structure.

I am attaching two images which show the output for data and for Part:

Looks like the file has been imported as a single String rather than a List of lists. Also looks like the columns in the file are TAB separated. If so, try

data = Import["Data1.txt", "TSV"]
data[[2,2]]

Thank you, that has worked!
