Modules I have installed:
Chaos Tools Suite
SWF Tools

Display youtube videos on website.

Functional issue:
Only the first video displays.

Methods used:
I created a custom content type with file fields. While adding these fields I got

warning: Illegal string offset 'parent' in C:\wamp\www\test123\sites\all\modules\cck\modules\fieldgroup\fieldgroup.module on line 442.

I ignored this and continued. I began uploading videos I'd converted to .flv format. I changed the max file size via php.ini to 10 or 20MB via instructions on another post. I also applied and extended patches that I'd found. This meant changing &$methods, &$vars to $methods, $vars. I did this throughout the entire swtools module. I successfully uploaded a video. I can upload more , but instead of playing these videos, I get a message:
"Could not display the flash because does not appear to exist."
"You are missing some Flash content that should appear here! Perhaps your browser cannot display it, or maybe it did not initialize correctly."
Thank you for any ideas. I do not know php, but if anyone knows of a patch with clear enough instructions I'm willing to try that to.

I am posting this here because in the forum I was told
"The error however, is being thrown by fieldgroup in CCK which likely needs to be updated to work with the version of PHP in use."

Thanks for any help.
