Hi there, I’ve hit an issue trying to update an item in an array within an object variable using partial update. Here is the Object with the element I’m trying to update highlighted: And I’ve added the relative path in the formula ![Partial-update---Object](https://us1.discourse-cdn.com/flex016/uploads/weweb/original/2X/f/fa504d7a350d87ad91298318fc3618cf882ffbc4.jpeg) I can see that I’m targeting the correct element, as the result is being read correctly, however when testing, the element is not updating. I feel like I’m making a rookie mistake here. Any advice would be most helpful. 😉 ---

Hi! I have two thoughts: - The update is pretty deep in you object structure. Maybe the “Partial Update” has a limit. If so, you can do this via Javascript - You are using different indices (`item.parent.parent.index`, `item.parent.index` and `item.index`). Are you sure this is correct? ---

Hey Max, thank you for your feedback, Based on the object structure i think the indices correspond accordingly: item.index = ratings item.parent.index = bars item.parent.parent.index = data I can use partial update formula to update items at the first level, but I can’t seem to update items at 2nd or 3rd. I’ll try the JS route as per your suggestion. ---

Odd, There has just been a application maintenance and now the item menu has disappeared! ![Screenshot 2023-09-14 at 17.56.53](https://us1.discourse-cdn.com/flex016/uploads/weweb/original/2X/5/53aa87e19b510dc569541a596179272ad27b9c52.png) I now have no access to the scope of the current item. ---

Are you trying to update a value in a collection item? `area_attribute_result_object` if so, that’s not how you’d do it. They are read only afaik. You’d need to make an update call to your backend. ---

Go to custom javascript and do this **[area\_attribute\_result\_obj.data][item.parent.parent.index].bars[item.parent.index].ratings[item.index].result = true** or if you have it within the context, you can directly target the result, you might see it there **[result] = true** if you want to do it via path, you gotta do it like a string I think. Now you are changing **[area\_attribute\_result\_obj]false** ---

Thanks Broberto, Super helpful … using Custom Javascript worked. Using the context item made it super simple too. context.item.data.result = true Big thanks 🙂 🤩 ---

I know this is old topic. This problem stole my whole afternoon, but I found a solution. For anyone who want to stick with no-code way, and don’t want to go custom Javascript. Since [this hero](https://community.weweb.io/t/partial-update-of-an-array-within-object/3011/3) mentioned that the “path” property of the partial update uses RELATIVE path. I solved that by convert the whole dynamic relative path to a string, then return it 😀. ![image](https://us1.discourse-cdn.com/flex016/uploads/weweb/original/2X/5/5022d6303f7042fe1bb872cf5879bc01324133b7.png)
