Hi, I have a routine that renumber a category that I choose. But I want to choose the starting number… How can I change to choose in Dynamo Player, with a String? ![transferir](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/3/5/35886846321c58dcbf53737f68f9c3f1ef396b53.png) Thanks! ---

Certain nodes can be used as inputs in Dynamo Player. Just right-click the node and check “Is Input”. Then it should show it the Player properties. For a simple input like this, the built-in inputs should be good enough. For more advanced inputs and (in my opinion) a better user experience, look into Data-Shapes. ---

Pretty much what Nick said, but also make sure you replace your start number with a variable, then feed the player input into that. See attached. ![variable%20set](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/5/1/51cdedb19338feaaa93cdb854c3769935732a3f1.jpeg)
