# Rearranging Tips ## Cascading rearranged Variables In the [**previous section's**](/rearranging/rearranging-example.md) simple walkthrough, we only have three Variables, `Revenues`, `Widgets sold`, and `Price`. Most situations are more complex than this: for instance, take the example below, where `Widgets sold` incorporates an inflation Calculation (`Widgets sold = Widgets sold [-1] * (1 + Widget sales yearly increase)`.

We see the same warning in the `Revenues` as previously **(1)**: we need to rearrange a child. However, this time, when we rearrange `Widgets sold`, we see a similar warning in `Widgets sold`, as shown below **(2)**.

Models is telling us that now we are calculating `Widgets sold` from `Revenues` and `Price`, we cannot also calculate it from the inflation calculation. Therefore we must rearrange `Widget sales yearly increase`, which can be calculated from the actual values of `Widgets sold` in 2021 and 2022. This results in the below output with `Widget sales yearly increase` also rearranged **(3)**.

In this way, rearranged Variables cascade down to the "bottom" of the Model, or the point at which there are no more Calculations to rearrange. ## Reversing relationships Models allows you to quickly change the direction of calculation flows if you change the desired output of a Model. Take the below example, where we have set our Model up with `Revenue` as the output from the two input Variables, `Widgets sold` and `Price`.

If we select both **(1)** the `Revenues` Variable, and one of its child Variables (in the example above, `Widgets sold`), we are offered the option to reverse their relationship, using the **Reverse relationship** button **(2)**. This results in the below:

`Widgets sold` has been converted to a Calculation Variable with Calculation `Revenues / Price` **(3)**. `Revenues` has been converted to an Assumptions Variable where the second Time Segment is now rearranged **(4)** to its original Calculation of `Price * Widgets sold`. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
