Problem in submitting the solution


When I tried submitting the solution I’m getting
"Invalid headers. Headers should be User_ID, Product_ID and Purchase"
but the headers should be ‘Item_Identifier’,‘Outlet_Identifier’,'Item_Outlet_Sales’
as per the sample submission provided.
Any suggestions

Hi I have finished typing the code in R format. Now I can’t seem to figure out this Solution Checker format. My format is completely different from the prescribed format i.e. SampleSubmission format. I am not getting these heades i.e.
Item_Identifier,Outlet_Identifier and Item_Outlet_Sales. Can somebody please help me out with this?
