select command to set a choice in drop down of a subform

select command to set a choice in drop down of a subform

Hi,

I have a drop down list in subform which is dynamically populated when the record is added.
However when the record is edited, only the selected option remains and other other options are removed from the drop down so the user is not able to select another option. I do not know why the drop down is not populated. As a I am re-populating the drop down, the original selection is lost. 

When I try to save the selection to a variable and then use select command to assign the same option, it gives error and the select option is not supported. Is there any way to re-populate the list and select the earlier option.

Thanks for any help,.
