Problem with creating a launcher

[EdN]

I am trying to create a launcher in Fedora 13 which will run a simple script named proj4a. I run this script from the command line as follows:
$ /home/enowak/proj4a >/home/enowak/proj4a_out
where proj4a is an executable file in my home directory and the output goes into a file, proj4a_out, in my home directory. Everything works fine.
I created a launcher called Proj4a and in the command field I entered the following:
' /home/enowak/proj4a >/home/enowak/proj4a_out'
When I click on the launcher it comes back with the following:
There was an error launching the application.
Details: Failed to execute child process "/home/enowaki/proj4a >/home/enowak/proj4a_out" (No such file or directory)
I can't for the life of me figure out what is wrong here. Does anybody see what I'm missing?
