Question : Data Validation based on two values X and "Blank"

I need to incorporate two options in a DV list  X or blank.  ive tried placing a space , X in the DV list source field but i only see the X in my drop down menu.  any ideas of how this can be done? preferably without a macro.

Answer : Data Validation based on two values X and "Blank"

To include a space or blank you need to use a range reference versus a list of constants. To enter a reference to a list of cells containing the possible values enter an equal sign followed by the cell reference:

   =$A$1:$A$10
