Replace variable in awk print statement

        while [ $Count -le $FILE_COUNT ]
                File=`grep ${ENTITY}"|" $CFG_FILE | awk '{print $Count}'`
                Count=`expr $Count + 1`

Problem is that I want to replace "$Count" with "$2" and so forth.
I tried setting TEST="'{print \$$Count}'"
then     File=`grep ${ENTITY}"|" $CFG_FILE | awk $TEST`

Although $TEST prints correectly, the content of $File is the entire line

The $CFG_FILE has content like this:   ABC01|     a.txt     b.txt

I want File to be equal to a.txt on the first pass
then b.txt on the 2nd pass in the while loop.
