MI-L Flexible Dialogs

[Marco Kok]

Hi All,
 
I'm trying to create a Dialog which displays all the columns in a previously
selected table. They need to be displayed separately. 
The code I'm trying;
 
        nCols = NumCols(SelectedTable)
 
        Dialog
                Title "Columns"
                For i = 1 To nCols
                        Control CheckBox
                                Title
ColumnInfo(SelectedTable,"COL"+i,COL_INFO_NAME)
                Next
 
But this doesn't work. Is there a way to make this work?
 
Thanks,
Marco Kok
