Is it the correct url?
I put \ for quates to make it as a php block.
<!-- BEGIN Help Center Live Code, Copyright (c) 2005 Help Center Live. All Rights Reserved -->
<a href=\"modules. php?name=eHelp\" target=\"_self\"><img src=\"http: www. ebizdom. com/ehelp/live/icon. php\" alt=\"Click here for Live Help - Powered by Help Center Live\" /></a>
<!-- END Help Center Live Code, Copyright (c) 2005 Help Center Live. All Rights Reserved -->";
Okay, two things to say. . .
1. I see you have corrected the "hxxp" to "http" so that's is a very serious fix in this matter.
2. As for the PHP coding. If you must place the CODE in your PHP code, then perhaps. But, I question why you would need to do that. Most CMS, and other PHP based CODED systems will have bits of HTML TAGS like <header> <body> <tr> <td> <center> <font> etc. a good place to put NONE php modified CODE EXACTLY like the HCL software generates for you, no changes.
I find it works well to paste the CODE just be for the </body> TAG, though I have been known to use it just after the <body> TAG. The reason I tend to go just before the </body> is because I notice some PHP based systems, or perahps some severs?, if I place the code right after the <body> TAG, it will cause the page to move up and down as it refreshes, and i don't like that. But placed at the end, just before the </body> TAG i never have this problem.
Again, I really think, from my experience so far, that recoding for PHP the way your showing it, may be the source of your problem. So, try my suggestion for kicks.
If you like to give me a URL where you have been trying to make it work, I could look closer if you like.
Have a great evening.
