There is no path to your file, cron is the most dumb program you will find.. it has a very minimalist environment so all has to be given...

You need to cd to where the files are.
Also cat means concatenation, so you can do the same in one stroke
Code:
#!/bin/bash
if cd /path/to/the/files
then
  DT1=`date +%Y%m%d`
  echo "Off      PP          TT" >>summary_$DT1.txt
  cat ues{1,2,3,4,5,6}.txt_$DT1 >>summary_$DT1.txt
fi
