You've to assign an array name to the RowSource. Try

Thisform.popattached.RowSource = "parray"

>this can't be rocket science and I'm sure I've done it elsewhere but I can't seem to find a working example. The following code appears to work, but I'm not seeing anything in the popup:
>

>attachfile=Getfile()
>If Empty(Thisform.popattached.RowSource)
>	Public Array parray(1)
>Else
>	Dimension parray(Alen(parray)+1)
>Endif
>
>If Not Empty(attachfile)
>	If Empty(parray(Alen(parray)))
>		parray(Alen(parray))=attachfile
>	Endif
>Endif
>If Empty(Thisform.popattached.RowSource)
>	Thisform.popattached.RowSource=parray
>	Thisform.popattached.RowSourceType= 5
>Endif
>
>Thisform.popattached.Requery
>Thisform.Refresh

>I can see all the values being properly assigned and stored in the array. The value of the rowsource is confusing me. Instead of showing "parray" the name of the array that I've assigned to rowsource, I'm getting the first row of the array only.
