how to set a bindkey to display multiple layers ?

Hi, 

I am using cadence 6.1. I am trying to set a bindkey to display certain layers at 1 time. For example key '0' will display base layers, key'1' will display metal1 via2 and metal 2 . I have a simple setup like below but it didn't work. I am not sure what is the missing in this code ? I am new skill code 

thanks

hiSetBindKeys( "Layout" list(

 list("<key>1" "pteSetNoneVisible() leSetEntryLayer(list(\"M0\" \"drawing\")) leSetEntryLayer(list(\"M0\" \"pin\")) letSetEntryLayer(list(\"VIA0\" \"drawing\")) leSetEntryLayer(list(\"M1\" \"drawing\")) leSetEntryLayer(list(\"M1\" \"pin\")) leSetEntryLayer(list(\"CM1A\" \"drawing\")) leSetEntryLayer(list(\"CM1B\" \"drawing\")) leSetEntryLayer(list(\"prBoundary\" \"boundary\")) hiRedraw()")
 list("<key>2" "pteSetNoneVisible() leSetEntryLayer(list(\"M1\" \"drawing\")) leSetEntryLayer(list(\"M1\" \"pin\")) letSetEntryLayer(list(\"VIA1\" \"drawing\")) leSetEntryLayer(list(\"M2\" \"drawing\")) leSetEntryLayer(list(\"M2\" \"pin\")) leSetEntryLayer(list(\"CM2B\" \"drawing\")) leSetEntryLayer(list(\"prBoundary\" \"boundary\")) hiRedraw()")
