Margaret,

The Connect2SQL() method should be called from within a method of the objDataType class, such as the init(). See below...

>The 'invalid subscript reference' pops up on the 3rd line shown below when the objdatatype tries to go to goapp.

>    lnConn = 0
     procedure init
>        this.lnConn = goApp.Connect2SQL('CHROMM')
     endproc
...
enddefine
