I want my code to be as clean as possible and therefore made option 2 as below, but is it the same as option 1? I can’t check it with a watchnode as it mentions: UI.IntegerSlider input, but there seems to be a difference. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/5/b/5b0d8e80fb1905a9569b48b2f7a34e7321ecae14.png) ---

Why not use the Dynamo OOTB slider? Or is this for Data Shapes? Do you want three different sliders in the end? > but there seems to be a difference. In what? ---

Yes, it’s input for datashapes. When I exchange the code in the red box, the tool doesn’t work anymore ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/4/f/4fd552789398d775414d3e9f4402278ad35f101e.jpeg) ---

Yeah this should work the same ---

How does it not work the same? Can you show what the datashapes output looks like before, for option 1 and after with option 2? ---

It looks like it could be an issue with how you pass your inputs into the following nodes (circled in green). ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/f/c/fc67514ee0e8472631be2c97edbb6e9733b185ed.png) Try setting that node to lacing longest, or repeat the title string included in the codeblock 3 times also. ---

It does seem to be a list problem: ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/3/e/3e1e9384f2f7844c32b39def25ba52095512a8c7.png) ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/e/c/ec29ecb0b4ab86a4257164a6d57f82026020ffc3.png) ---

You have 6 inputs into your MultipleInputForm. You need to narrow down which one is the cause of this issue. I’d recommend doing some debugging, plugging in 1 input at a time into the MultipleInputForm until you get this error. Once you have this you can narrow down the cause of this issue. ---

Well I didn’t change the rest of the code, but after removing the other 5 inputs I still get this warning. I guess that the UI.slider can’t handle multiple inputs. My knowledge of Python is limited. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/1/4/149b1f9eb1686d39723ca8f279e3873ea8737188.png) ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/0/9/09cdf0da7007a7b203af1d67994a4c406c358916.png) ---

For some reason, minimum and maximum dont need repeating in the list: ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/e/d/ed8cfad61a4ed18dfdd2534ec8f239a1584657d6.png) ---
