When I call the run_actuals method in Unix Server. It ran a file named web.template and output the result to the file web.template.output. This is exactly what i typed in unix server: 
( /GPP/bin/run_actuals web.template & )

in case you wanted to know, the file web.template is in cgi-bin. It works perfect. But I could not run the same method from inside my cgi script. The command I gave to call and run the file is this: 
system("/GPP/bin/run_actuals /GPP/web/cgi-bin/web.template");

I moved the web.template file away from cgi-bin and tried to run it again. but I still could run the method inside my CGI script.
I don't understand why I can run the same method manually on the Unix Server, but I cannot run it from my CGI script...
Thanks in advance, if you know the answer
