Why am I unable to set organization name?
crmGetAttribute is not in 4.4, that only exists in later versions of CiviCRM. So either:


You are using an extension that is not compatible with 4.4, or
You have copied a template file from a later version of CiviCRM onto your install, or
You have somehow managed to get your 4.4 files mixed up with code from a later version


The best solution for any of these situations would be for you to upgrade to the latest version of CiviCRM. If you follow the upgrade procedure correctly, this will ensure you have a clean copy of the latest source code.
