Single file is not running in crontab ( ubuntu 16.04)

Below is my cron setting. How ever is not running , the next file is running. I dont understand why.

* * * * * /tmp/<file1>.sh
* * * * * /tmp/<file2>.sh

I have give the permission to the file chmod +x /tmp/ and chmod +x /tmp/

Ran below commands as well.

sudo service cron restart
sudo service cron start
