Brian,

If both cells F11 AND G11 are blank (ie "") then the result of this formula
will be blank.
This is the same with "?". That part of this formula is looking to see if
there is a ? in cell F11 and G11 and if there are, then the result will also
be blank.

I know these are multiple IF statements above, but I cant figure out what
the "" means?? eg. F11="". Does it mean if cell is blank then the cell
with
this formula is blank ?

What about the "? " eg. F11="?". Does it mean if cell has any text in it
the the cell with this formula is blank ?

Thank for any feed back!
