Hello everyone, I hope you are all doing good! I have a scenario wherein I have a router with 2 branches for conditions and a last one that serves as a converger. In the two condition branches, I need to keep track of the OpenAI’s API cost. As of now, I use an array aggregator to store every cost, but when the loop ends, I need to retrieve these arrays in the last branch (converger) to sum them. Does anyone know how this can be done ? Here is a picture of what the scenario looks like: ![image](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/1/a/1a265303baee3e8b163d4717d062de1f3fa2f90c.png) Thanks in advance for your help. ---

To “update” a variable, you basically need to get the variable’s current value first. To do this, you can try using the Tools “ **Get multiple variables** ” module — > Get values of a previously stored variables. For more information about the Get multiple variables module and Tools app, see the corresponding [Integrations page](https://www.make.com/en/integrations/util) and the [Help Centre documentation](https://apps.make.com/util). Hope this helps! Let me know if there are any further questions or issues. — @samliew ---
