Hi all, I don’t know why it says"Warning: List.GetItemAtIndex operation failed. ‘int’ object is unsubscriptable" how to fix this problem? Thanks! ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/e/7/e779323f8d62c4c8128f8b497a7f8b1bc0464047.png) it turns out there are two list.getatindex in my dynamo, one is original the other comes from Orchid package. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/b/2/b236bfcaef4f66270e72fb16226777363818be7d.png) ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/1/2/12f446109666f1d95cc71e73a60522da7624e1c3.png) but after i replaced with the with the original one.

Hi @dylanpeng, Your input is a nested list, so i think you need to add levels to the “List.GetItemAtIndex” node. ![Use%20levels](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/1/6/16dd59cc674ef9cff77fe6da098a4a1fd52338f0.png) More information can be found here.

Thanks Jonathan&mark, I have fixed the problem. There are two main things to fix within the script: 1. Inside the tool.createfromemptysheet.node, this script need to update to DSCore.List.Flatten ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/f/5/f5ab08818d11a90106b48097665df824dc729ef6.png) 2. Highlight in yellow color. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/e/c/ec56176153826cb2d79a6081c8acdb1a5c1d4c10.png) ---

Out of curiosity and continuity for your topic… Which package is the “Tool.CreateEmptySheet”-node from? 🙂 Glad you fixed your issue. ---

It is from the SteamNodes package. ---

I’ll just tag @Julien_Benoit1 as he is the owner of SteamNodes, to make the update of his package to 2.0 easier. 🙂
