	You have indicated that you wish to integrate FlashChat with <b><?php echo $cmss[$useCMS];?></b>. Please refer to the full integration instructions located

	The correct login values for your MySQL server should be auto-entered into the form below. If they are not, then you should check to ensure that FlashChat

		<b>Configuration Error!</b><br><br>
		FlashChat was unable to detect your MySQL login setting from the <b><?php echo $cmss[$useCMS];?></b> configuration file. You must correct this before FlashChat can finish its installation.
		Please refer to the integration Instructions in the <a href="http://www.tufat.com/wiki/" target="_blank">TUFaT.com Wiki</a> to ensure that the FlashChat files were correctly uploaded to your server.
		<br><br>
		Possible Reasons for this error may include:<br><br>

		1) FlashChat was uploaded to an incorrect server location.<br>
		2) The CMS system that you are using is unsupported by FlashChat.<br>
		3) Your server has incompatible settings which may have been undetected in Step 1 of the FlashChat installer. For example, specific security restrictions which are not typical of most PHP/MySQL setups.
