NEED HELP URGENTLY

I SETUP THE PHP PARSE ENGINE ON ABOUT A YEAR AGO ON ONE OF MY WEB SERVERS AND EVERYTHING WORKED JUST FINE. I, HOWEVER, RECENTLY ACQUIRED A NEW SERVER AND TRIED TO SETUP PHP AGAIN ON IIS 5.0 ON A WIN 2K SERVER PLATFORM. EVERYTHING SEEMS TO BE WORKING CORRECTLY, BUT FOR SOME REASONS WHEN I TRY TO ACCESS ANY VARIABLES PASSED FROM A HTML FORM, I ALWAYS GET AN ERROR. FOR EXAMPLE IF I HAVE A FORM THAT PASSES THE VARIABLE $ACTION I GET THE FOLLOW ERROR WHEN I TRY TO ACCESS THE SAME VARIABLE IN PHP PAGE: Notice: Undefined variable: action in C:\...\otelzoo.com\cust_care.php on line 9 I HAVE REINSTALLED THE PHP PARSER THREE TIMES NOW AND I HAVE HAD NO LUCK IN GETTING RID OF THIS PROBLEM. I KNOW MOST PEOPLE WILL JUMP TO THE CONCLUSION THAT THERE IS A SIMPLE ERROR IN THE ACTUAL SOURCE CODE ITSELF, BUT I PROMISE YOU THAT I HAVE BEEN PROGRAMMING IN THIS LANGUAGE FOR AT LEAST TWO YEARS AND I AM 100% SURE THAT I AM PASSING THE VARIABLE CORRECTLY. PLEASE HELP. THANK YOU. - DALE
