 <p>Change your formula for the following:</p> <pre><code>=INDIRECT(CONCATENATE("FAB!U",(1638+((ROW()-1)*43)))) </code></pre> <p>You will need to play with this to get the outcome you desire. Imagine the above was put into cell A1, 1638 is the first row in your question, add on 43 times the row you are on minus one. So first row is 1, minus 1 is 0, 0*43 is 0, so you are still left with 1638.</p> <p>Move to the second row and it is 1638, add your row 2, minus 1 gives you 1, 1 * 43 is 43, so you have 1638+43=1681.</p> <p>Concatenate just joins <code>FAB!U</code> with the outcome of that formula.</p> <p>Indirect makes it a cell reference.</p> <p>Try to understand and have a play before just putting sticking it in.</p>
