Dear list - When I run the following code, the results are preceded by at least one screen full of blank lines. I am showing you a large code block since I do not know where the error is:

Help and advice, please Ethan If this is the ACTUAL code you are executing you need to remember to NOT include any blank lines. Each and every one gets echoed to the client and with all the blank lines I see above, that could very well be a full but empty page.
