Can you have a text variable shown within a text node?

Question

I am trying to a text node, where to states the user's name they chose at the start through a textbox to be displayed within a text node and wondering if it is possible. This is what I've done so far and it isn't working. Also, a unique piece of dialogue comes up if named Andrew.

      //if statement to determine the users name and save it
      if (nextTextNodeId == 60) {
      var InputName = document.getElementById('name').value
      name = InputName
      setState: { InputName: name }
      if (name == "Andrew") {
          ToggleInputOff()
          state = Object.assign(state, option.setState)
          showTextNode(4)
          return;
      }
      else if (name == "") {
          state = Object.assign(state, option.setState)
          showTextNode(3)
          return; 
      }
      else {
          ToggleInputOff()
          state = Object.assign(state, option.setState)
          showTextNode(5)
          return;
      }
      return ToggleInputOff()
      }

      //Example
        {
            id: 5,
            text: "Welcome " + name + " let us start the day!",
            options: [
                {
                    text: "Let's go",
                    nextText: 6
                }

            ]
        },
