Can anyone see why this code is not opening the table custs?

local os, od, oc
os=create('ss')
os.od.oc.getdata
os=null

define class ss as session
od=null
datasession = 2
function init
this.od=create('dd')
endfunc
enddefine

define class dd as dataenvironment
autoopentables=.t.
function init
this.addobject('oc','cc')
with this.oc
.cursorsource="custs"
.database="test"
.order="lname"
.alias="custs"
endwith
endfunc
enddefine

define class cc as cursor
function getdata
wait window 'Testing...'+custs.cust+':'+custs.lname
skip
wait window 'Testing...'+custs.cust+':'+custs.lname
endfunc
enddefine
