No gene can be mapped

[diploidcc]

I specified in the input that I'm using gene names but keep getting the following error.

Warning in bitr(input$gene, fromType = fromType, toType = toType.list, OrgDb = eval(parse(text = org.db.name))) :
2.28% of input gene IDs are fail to map...
--> No gene can be mapped....
--> Expected input gene ID: 389320,83983,7026,9698,51087,6847
--> return NULL...
