I'm modifying an existing workbook. One of my drop down lists has its
text options provided by means of a 'Defined Name': Choices.
The Name 'Choices' refers to the text items in a group of adjacent
cells, in a row, on another worksheet called 'Info'. The reference is a
range: ='Info'!$D$7:$H$7

I want to add an extra item of text to increase the number of options
in the drop down list. So as not to disturb the location of cells
defined by other references, I tried to append the new cell downwards
from the group in the row.
I tried this: ='Info'!$D$7:$H$7,$D$8

It didn't work so I went for the range extending
option:='Info'!$D$7:$I$7
This worked OK but it's using the 'I' column which was a spacer between
another block of data. So, if I want to add more options later I'll
have to go elsewhere to avoid messing up other absolute references.

Please can anyone explain the syntax used for adding a remote cell
location to the original range:='Info'!$D$7:$H$7?
TIA
