Troubleshooting Google Apps Script: How to Ensure All Functions Run Together

If you're working with Google Apps Script, you might encounter situations where your functions perform perfectly when executed in isolation, but fail to run properly when combined. This is a common problem and can be quite frustrating, especially if you're still learning how to script. In this guide, we’ll explore why this happens and how you can resolve it effectively.

The Issue: Functions Failing to Run Together

A user reported an issue with their script where three functions were designed to execute sequentially, yet only two would run when called together. The problematic function, medewerkerLijst, executed flawlessly when run separately but refused to cooperate in the combined execution. The other functions, nieuwDossier and sorteerDossiers, worked perfectly.

Analyzing the Functions

Let’s take a closer look at each function to identify potential issues:

medewerkerLijst:

This function copies a range from one sheet to another.

It operates with a static source and destination which could potentially conflict with the operations of other functions.

nieuwDossier:

This function copies a template sheet and renames it based on a cell's value.

It creates a new sheet, which could impact the state of the spreadsheet if not handled properly.

sorteerDossiers:

It sorts the sheets in the spreadsheet.

If medewerkerLijst relies on a specific state of the sheets, changes made by this function could lead to errors.

Solution: Modifying the Script

To ensure all functions run together without issues, we can re-structure your script. Below is a modified version of the original functions, which combines the logic into a single cohesive function, ensuring smooth execution:

Key Changes Made:

Single Function Call: Instead of calling separate functions, all logic is encapsulated in a single main function. This ensures that the changes made for copying and creating sheets don’t interfere with one another.

Simplified Logic: Combined logic helps in reducing the risk of errors due to order of execution or state dependencies.

Conclusion

Debugging code can be a challenging but rewarding experience, especially when learning Google Apps Script. By consolidating your functions into a more cohesive structure, you not only streamline your code but also enhance its reliability. If you encounter Further issues, consider checking for dependencies between the functions and ensure that the operations performed do not conflict with each other.

Next time, when you write your scripts, keep in mind the structure and flow of execution to help avoid similar issues. Happy scripting!
