Setting up crontab, still cant get it to work

OK I have been working on this simple action for a while and I cannot get it to work.
First off im new to the linux command line world. I feel like I am missing something simple.

What I am trying to achieve is that I want this command:

Code:
tcpdump -s2000 -w'flowroute-%H%M.pcap' -G900 -W36 &

to run at 0800 Monday through Friday.

I have setup a crontab that reads:

Code:
0 8 * * 1,2,3,4,5 /root/crontab.txt

the text file I'm using to run the command just says:

Code:
#captures packets in 15min segments and stops after 36 segments
#cronjob is setup for starting at 800 and then would go until 1700
tcpdump -s2000 -w'flowroute-%H%M.pcap' -G900 -W36

I have set the txt as an executable. Im running this from the root.
I have also try adding in an escape character breaks to compensate for the % symbol
what i mean:

Code:
tcpdump -s2000 -w'flowroute-\%H\%M.pcap' -G900 -W36

If any one has any suggestions or ideas for what i could do?
Currently this doesn't do any thing.

Linux::Distribution::Packages(3pm)			User Contributed Perl Documentation			Linux::Distribution::Packages(3pm)

NAME
Linux::Distribution::Packages - list all packages on various Linux distributions SYNOPSIS
use Linux::Distribution::Packages qw(distribution_packages distribution_write); $linux = new Linux::Distribution::Packages({'format' => 'csv', 'output_file' => 'packages.csv'}); $linux->distribution_write(); # Or you can (re)set the options when you write. $linux->distribution_write({'format' => 'xml', 'output_file' => 'packages.xml'}); # If you want to reload the package data $linux->distribution_packages(); DESCRIPTION
This is a simple module that uses Linux::Distribution to guess the linux distribution and then uses the correct commands to list all the packages on the system and then output them in one of three formats: native, csv, and xml. Distributions currently working: debian, ubuntu, fedora, redhat, suse, gentoo, slackware, redflag. The module inherits from Linux::Distribution, so can also use its calls. EXPORT None by default. TODO
* Add the capability to correctly get packages for all recognized distributions. * Seperate out parsing from writing. Parse data to hash and give access to hash. Then write the formatted data from the hash. AUTHORS
