Strange error


11:41:21.021 - Expression Exception - in C:\JRun4\servers\cfusion\cfusion-ear\cfusion-war\WEB-INF\cfusion\CustomTags\com\adobe\coldfusion\base.cfc : line 375

	    Cannot find qryname72171 key in structure.

11:41:21.021 - Expression Exception - in D:\apache\htdocs\anga\handlers\login.cfc : line 368

	    Element 1510119388806 is undefined in a CFML structure referenced as part of an expression.

11:41:21.021 - MissingInclude Exception - in D:\apache\htdocs\ColdBox\system\plugins\Renderer.cfc : line 271

	    Could not find the included template /anga/views/login/dologin.cfm.

How can I figure out what this error means?  I am not seeing anything bad near or at line 368 in login.cfc?

I found the answer but it was not related to the code I was looking at there was a function put in by a different programmer I commented it out and everything is working now.
