To add a default path to the stock code, need to add a record 50 to Images & Forms, then put the path into LookupString, which is the field just below the Footer band.

-Admin - Configuration - Images/Forms

All this does is prefix the Stock Code with the SharePoint String.

  •   IMAG:Unique = 50
      Get(IMAG,IMAG:KeyUnique)
      L_LookUpLink = Clip(IMAG:LookUpString)&Clip(STSH:CODE)
