Hello using bash- Linux

I have a file which has the following format

input_file: 1980 04:50:59.00 23.500 32.150 1990 05:47:50.02 50.000 52.940 ..... and goes on

I have to ask the user to insert the time of interest and the maximum distance then create an outpout file with the same format as the input but the region should been in a range between +- maxdistance

script:

read time_of_interest

read distance_max

awk ' if ($3<=$3+$distance_max && $3>=$3-distance_max && $4<=$4+distance_max && $4>=$4+distance_max) {printf "%s %s %s %s %s %s", $1,$2,$3,$4,$5,$6}'' ${myfile}> ${myfile_out}

but this doesnt work

Some help with the script???

Thank you in advance
