Unknown constructor 'attachController.attachController(ApexPages.StandardController controller)'

Trying to build a webpage for teams to be able to submit cases and attachments. For some reason I am getting a "Unknown constructor 'attachController.attachController(ApexPages.StandardController controller)'" error and even though I add the standard set controller I am still getting an error. Am I missing something on this for where I need to be adding this? 

VF: 
<apex:page Standardcontroller="Case" extensions="attachController" showheader="false" >

Hi you need to define your controller as:
public attachController(ApexPages.StandardController std){

}

Thanks for that Bishal. I am now getting an error:
Could not resolve field 'Name' from <apex:inputField> value binding '{!cs.Name}' in page ProductCaseExternal

If I remove the visualforce for the attachment my visualforce saves but the attachment is the whole reason I have the extension.
