>I GET Cannot acces the table

Several possible things: your table is closed somewhere; it lives in a different data session; another cursor with the same name is created elsewhere.

What I usually do is to have a property of the combo named cAlias, so my combo.init looks something like this:

this.cAlias=sys(2014)
select *... into cursor (this.cAlias)
this.rowsourcetype=6
this.rowsource=this.cAlias+".field1,field2"

This way the cursor is there for combo's private use, and nothing touches it.
