Can't execute a script

[bob self]

I have a simple test script called 'scripttest' in /root/bin:

-rwxr-xr-x  1 root  wheel  121 Sep  9 14:55 scripttest

my $PATH IS
    
/sbin:/bin:/usr/sbin:/usr/bin:/usr/games:/usr/local/sbin:/usr/local/bin:/usr/X11R6/bin:*/root/bin*


#!/bin/sh
echo "pinging...."
#end of scripttest

If I run "which scripttest", I get /root/bin/scripttest

But if I try to run this test script I get "scripttest: Command not found."

Why is that happening?

thanks,
