@pedroSU62A While you could try some alternate _Lacing_ options, it would help if more information is provided (files, images with expanded preview bubbles, etc) ---

Hi @pedroSU62A The script alone is not helpful - Need the Excel too as that appears to be the starting point… And will explain what is trying to be achieved. ---

Hi @pedroSU62A Needed to change the Link to the Excel (file name is different) Needed to change the Input (Excel sheet name is different) Assuming those are not the issue; this is what @Mostafa_El_Ayoubi was asking ![](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/b/a/baa62d8ff6e56777c118fd92b2e33b528c598e9d.png) Think it’s self-explanatory… Unless your error at that node is different… One of the level names (does not match between Revit & Excel) Ok - Reason is that the I ran the script by opening a new file off the standard template… So it didn’t have a level by name **Level 0** 🙂 ---

Hi @pedroSU62A Ok the script runs fine except for the last portion of setting up parameters (probably because my Default Revit file doesn’t have those specific project/shared parameters) So - if you restart Revit & Dynamo (assume it is the issue of cache not getting cleared), and then re-run the script It should work fine! ---

Hi @Chandrasekar_Rajaman : yes the link and the input are correct the only thing that i didnt save in the script the file i have sent you (script and excell). On the other hand, the levels are the same in the excel and in the project that i have double checked, for that reason it seems really weird this problem, when i was using this script for months without any problem. This week is the first time I have the error “Warning: One or more of the input types are not matching. Couldn’t find a version of ByLevel that takes arguments of type (\_\_array)” ---

@pedroSU62A The script creates a copy of one floor plan per level (2 levels in my sample file) & names it with a value from Excel. But I don’t get the error. However, I could see there is an input of 158… So a bit unclear - Can you confirm the output you are expecting? Did you also try changing the Lacing as suggested by Vikram? ---

@pedroSU62A Of course; that’s why I was wondering if more was expected from the script… It worked more than once; so nothing wrong with the script 🙂 ---

@pedroSU62A I didn’t save the file - But if u want to; I can (create again &) send you the sample project files 🙂 BTW, Can you start a new project off the Archi Template & try running the script? If you have not done it already? That’s what I did & it worked… after I renamed the levels to be Zero & One
