No problem! :-)

Assume you have a droplist like this:

tlb=widget_base()
items=['Cancel','OK']
droplist=widget_droplist(tlb, value=items, uvalue=items,
event_pro='droplist_Event')

widget_control,tlb,/realize

; What index does 'OK' have
indx = where(items EQ 'OK')

;;; This is BAD, because where returns a lonarr and you need a single
value
; Set the current value in the droplist
widget_control,stations_list,set_droplist_select=indx(0)

What can be tricky is to obtain the right droplist ID. Use the
widget_info (with the parent, child, sibling or whatever keyword)
function for this.

Enjoy!
