Method Image Parameter Input

When creating a Method Image, you can type: [ASK] in to parameter 1 or parameter 2 or both. Then when you click on the image in the screens app or on the screens page of the web UI, you will be prompted for a value before the method gets executed.

If you leave the Parameter blank, or enter any other data, the Method Image will execute the method normally as it did before.

The screen app actually uses an additional control that Pops Up when you click the image.
The Web UI just uses a Javascript Prompt for the input.
