Hello experts,

Have anyone use the PHP Fundraising Thermometer: http://sourceforge.net/projects/phpfundthermo/

I tried to create the thermometer, but I am just getting the source code on the screen.
Can someone please help?

Thanks.

If you are seeing the source code that means your server doesn't understand PHP or you are not running the page through a server.
How are you loading the page in the browser? What server are you using?

I am running on an Apache server and I have created multiple php pages and are able to view the results of the php.  I am viewing it via Firefox on the web server that I do with my other pages.  Not sure what it is giving me problem.  Here is the code:
<?
/*
     Fundraising Thermometer Generator v1.1
     Sairam Suresh sai1138@yahoo.com / www.entropyfarm.org
    
     NOTE - you must include the full path to the truetype font on your system below 
            if you want text labels to appear on your graph. No TrueType fonts are
            included in this package, you can probably find some on your system or
            else download one off the net.
      

     Inputs: 'unit'    - the ascii value of the currency unit. By default 36 ($)
                         other interesting ones are:
                           163:  British Pound
                           165:  Japanese Yen
                           8355: French Franc
                           8364: Euro

             'max'     - the goal
             'current' - the current amount raised

     Versions:
     1.2 - added a 'burst' image on request, cleaned up the images a little bit.
     1.1 - Internationalized :) added 'unit' at a user's request so other currencies could be used.
     1.0 - intial version

You don't have short open tags enabled so
<?

will not work, you will need to change it to
<?php

Bad coding on their part
