Shell Programming and Scripting

Hello, I have got the script below that reads a text file and then extract data from the third column and then send the result to another shell scrpt call tsim - the script works fine.
The problem I am having is that I want the user to enter the 'Test Day' which the first column in the text file, and depending on the Test Day entered (in this case 1, 2 or 4) the script will extract first instance of the required data from the related line, send the fist set of data to the tsim scrpt and then move on to the next.....CAN ANYONE HELP PLEASE

-----Current Script--------------------
#!/bin/sh
Please enter the Test Day - Enter 0 for all : "
read x
( read a b c d < LottWagers2.txt
IFS=-
printf ' 1\n 20\n 0\n 0\n 1\n 1\n 7\n 0\n'
printf ' %s\n' $c
printf ' 1\n 1\n 0\n 0\n 0\n N\n 1\n 100\n' ) |
"$LOTO"/bin/loto_tsim > /dev/null 2>&1
