However, as many users have noted, adapting code designed for one type of event to another can lead to unexpected errors. One common issue arises when trying to run code that utilizes the Undo method, often leading to the error: "Method 'Undo' of object '_Application' failed". In this guide, we will address how to successfully adapt your SelectionChange event code for the Calculate event without running into errors. Understanding the Problem In the scenario presented, the user attempted to modify their existing code, which operates successfully under the SelectionChange event, to work under the Calculate event. The following issues were noted: The original code was designed to change the color of a range of cells based on whether the filter mode was enabled or disabled. When adapted to the Calculate event, the user encountered an "Object required" error. The goal is to implement a solution without the previously mentioned issues while achieving a desired outcome on cell change. Overview of the Solution To adapt your SelectionChange code for use in the Calculate event, follow these organized steps: Step 1: Use a Reference Value We'll start by maintaining a reference value that will allow us to know when the specific cell (in this example, we'll use AL1) changes. This helps prevent unnecessary executions in the Calculate event and enables you to respond to changes specifically. Step 2: Set Up Variables Use the following code snippet as a template, which includes setting up a private variable to store the reference value and initializing it upon the activation of the worksheet. [[See Video to Reveal this Text or Code Snippet]] Step 3: Implement the Calculate Event Logic Within the Calculate event, you'll want to implement logic that triggers only when the value of AL1 changes, as outlined below: [[See Video to Reveal this Text or Code Snippet]] Step 4: Testing and Further Modifications Test the code to ensure it correctly changes the colors of the specified cell range based on the filter status whenever the calculated value in cell AL1 updates. If you need to check for more complex changes, you can expand the logic within the Calculate event, ensuring to still rely on the reference value mechanism. Conclusion Adapting code across different events in Excel VBA can be challenging, but with structured steps and clear logic, you can successfully make your existing SelectionChange code compatible with the Calculate event. By taking into account the requirement for a reference value, and using conditional checks based on changes, you can enhance the functionality of your Excel spreadsheets without running into errors.
