Hi Folks

Can anyone please tell me why I'm getting below error 

Error -  Unsupported attribute rightlabel in <apex:inputField>

My Code

<div class="form-group"> 

<label for="user-id" class="col-sm-3 control-label"> 

   Trace-App-Version

</label>

<div class="col-sm-9">                                                                                                    <apex:inputField styleClass="form-control" value="{!Settings.Trace_App_Version__c}" style=" width : 34%;"/>
