Greetings, The management of sheet names works in the same way as cell addresses. Whenever you give a cell address (like A3), a copy/paste of the cell to the next cell to the right will transform A3 into B3. To prevent that, you place a "$" sign in front of the column address, like: $A3. You can also make the row address absolute by placing a "$" in front of the row, like: A$3. And to make the cell reference absolute, you write its address like this: $A$3.
The same applies to sheet names. To prevent a copy from changing the referenced name, you place a "$" in front of the sheet address: $'Zip codes'.$A$2:$B$150. This must be done before the copy is performed. Please note that because you have blanks in your sheet names, you need to use the quote (this is probably why your example generated a #REF! error). Another way is to use named ranges. You highlight the cells you want to reference and you give them a name by typing in the name reference zone to the left of the formula. Once the name is stored, you can use that name directly in a formula. Names can then be managed from the selection in the Sheet menu. I hope this helps. Rémy.
