    <p>I have a spreadsheet where I would like to model the progress of several projects over a few years. The projects start in differing years.</p> <p>I have a table with years in the horizontal axis and projects on the vertical.</p> <p><img src="https://i.stack.imgur.com/w5PEj.png" alt="enter image description here"></p> <p>I need programatically to work out in which year each project starts. This was easy when the project line is static - I used a LOOKUP() function to connect the project number with the year number, but I would like to set-up various scenarios so that I can alter the schedule of projects on the fly from a preset list.</p> <p>This was easy enough - I just set-up another table with scenarios in the vertical and the projects on the horizontal, and pulled the correct row into the main table with an INDEX() function. </p> <p><img src="https://i.stack.imgur.com/yP7rg.png" alt="enter image description here"></p> <p>However, doing this seems to have screwed-up my ability to work out what year each project starts. The formula now gives very odd results.</p> <p>Is this because I am trying to LOOKUP() inside a range which has been pulled from somewhere else via an INDEX() call?</p> <p>If so, can anyone help me work out how to work around it? I don't understand why my formula is giving me such odd results.</p> <p><img src="https://i.stack.imgur.com/mj7ij.png" alt="enter image description here"></p> <p>If you want to see the spreadsheet it's available here:</p> <p><a href="http://diggory.net/Grazing/stackExchange/Index%20of%20lookup.xlsx" rel="nofollow noreferrer">http://diggory.net/Grazing/stackExchange/Index%20of%20lookup.xlsx</a></p> <p>Thanks in advance for any help.</p>

    1. COThe concept is kind of complicated to grasp; Sorry if my answer won't help, but maybe try using vlookup /or hlookup?

    2. COI have tried HLOOKUP() but it gave the same results. Sorry if I haven't explained it well enough. I am trying to get the spreadsheet to match the year number for the project number - i.e. in the bottom screenshot for the row which has '24' I would like it to find the value '9' because in the green row the value 24 appears in the same column as the value 9 in 'year' row.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
