I am new to dynamo and trying to learn it. It the early tutorials it keeps showing the number nodes and being able to put in 0…10. Well when i put that in, it does not like that and wants a whole number. Also i can not attach a number slider for example to a number node, only the number node to something else. Am i missing something, different node for this situation or what? ---

The tutorials show 0…10 then …#A or something along those lines, but my number node i can only put in whole numbers. ---

Hi, Show your attempts and use codeblock instead of the number node. ---

I am also new to using this forum so what do you mean show my attempts? And how do you use the code block? ---

Like this for example : ![Capture](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/9/e/9e332084f37e4837fc4649bc9a88b4791de8c8fe.png) ---

Now what about if trying to connect an integer or number slider to the code block? Is there a way to do that? ---

Use a letter to define a variable. You will have an input port in the codeblock. ---

Hi, I would highly recommend you to read the Dynamo Primer (we all went through it 🙂 ), especially the part about CodeBlocks : [http://primer.dynamobim.org/en/07\_Code-Block/7\_Code-Blocks-and-Design-Script.html](http://primer.dynamobim.org/en/07_Code-Block/7_Code-Blocks-and-Design-Script.html)
