Awk script not listing specific column

Using awk I have written this script but it's not working properly. Even I expected just only specific column it's displaying me total column of information. 

n=0
echo  "Enter which column you want: "
read  n
awk '{print $($n)}' out.txt

I would like to have only specific column for the value of n.

Thank you

There is no parameter substitution within single quotes. Use

awk '{print $'$n'}' out.txt

or use an awk variable as in

awk -v n="$n" '{print $n}' out.txt
