Making Size of Named Ranges Adapt

[AliGW]

I have an input worksheet into which I occasionally need to insert or delete rows. Any range defined in this sheet grows or shrinks accordingly, which is fine. However, on another sheet that reads from this input sheet, existing named ranges or defined ranges do not grow or shrink to match, so fomulae elsewhere that require ranges to be of the same size fail as soon as I add or delete rows on the input sheet. How can I make ranges on the related sheet grow or shrink automatically to match the input sheet? If this is not possible, how do I assign a fixed size to ranges and named ranges that will not respond dynamically?
