Hi Bill,

You can set an `id` for the input field, and use `document.getElementById('id of the input field')` to access it. For example:

- In the custom element:  
`<input type="text" id="user_name">`
- In an event:  
`var user_name = document.getElementById('user_name').value;`

You should double-click the Function field, select Add Function to add an event handler, and call the normal function in the handler:

```javascript
function yourEventHandler(doc, e) {
    yourNormalFunction();
}

```

Regards

Thank you Toan! I will try that.  
Love this software! The html widget and custom element add so much more. 😃
