please help me
Thanks in advance

That would be somewhat difficult to daignose as I have not used the software you are asking about. However, I believe the error refers to this line (75):

else $this->templatedir = $this->$default_template;

This is syntactically invalid, $default_template should not be prefixed by a dollar sign. It is possible that your server configuration is incompatible with the care2x software (ie: you may be running a too-recent version of PHP!).

A little information on the syntactic error can be found here: http://php.syntaxerrors.info/index.php?title=Cannot_access_empty_property

I would try and find the minimum system requirements for care2x, but their website is empty!

Care2X is open source software designed to integrate different information systems in healthcare organizations into a single system.

download link:
http://sourceforge.net/projects/care2002/

you can try to download it and install it.I remember when installing it gives me something on php versions.
Thanks in advance

Well I am quite aware what it is, but I am not going to download and install it. The issue you are experiencing is a syntax error - correct it or use a server configuration that is compatible with your software.

I correct the error but still have another problem:
Session: connection failed
can you suggest to me what to do?

Thanks for your help
