Array mistaken for a function

Hi, I'm posting this here because I'm obviously a beginner. If it belongs elsewhere, please let me know. TIA Now, I have a program that is comming along nicely, kudos to you folks here... but the following code causes me some problems. Com1 is a text field, & I want to set it to th i-th element of an array (Comment1), but I get a compiler error that Comment1(int) is not found in my class. Of course it's not, but what am I doing wrong. The second line works flawlessly.
Com1.setText(Comment1(Idx));
Com1.setText("Anything");
I've been thru several books & tutorials & I just don't seem to see HOW to set/get data into/out of a textField.

Thanks again, -Bill.

It should be
Com1.setText(Comment1[Idx]);
Use [] and not ()

Thank you so much for the help. I only regret not asking 6 hrs ago.

Thanks, -Bill.
