How to use WHILE loop to do processin in BASH

Hello,

I am stuck with coding a solution. Here is what I am trying to do.
Input file looks like this:
Rock - Franz Ferdinand - single - Do You Want To - 3:55 - 235 secs
Rock - Ani DiFranco - Reprieve - Millenium Theater - 3:14 - 194 secs
Rock - Enter The Haggis - Soapbox Heroes - New Monthly Flavour - 3:23 - 203 secs

My WHILE loop is coded as below, but it's not working. It ended up printing every row, instead of the rows than meet the criteria $col6 -le $val1
typeset -i var1=1000

while IFS="-" read col1 col2 col3 col4 col5 col6
do
if $col6 -le $val1;then
awk -F"-" '{print $1" - "$2" - "$3" - "$4" - "$5}' >> print.out
fi
done < data.dat

Can someone please help?
