I'm new to using Tk, and I am unable to run up a window I get:- START of error message>

couldn't connect to display "blue:0.0" at /opt/perl/lib/site_perl/5.6. +1/PA-RISC1.1-thread-multi/Tk/MainWindow.pm line 55. MainWindow->new() at .//test.pl line 4

<END of error message

I login to Sun M/C called 'blue' via citrix, then I rlogin into an HP M/C called 'red'( I'm not able to login directly to 'red'. The application is running on 'red' but I get the above error message, what should I be setting the DISPLAY var to on red to allow perl to generate the window. I've try ip address of both machinces and setting the display on red to the same a the display setting on the login window on 'blue' which is unix:18.0:0.0 Any Ideas
