A 'Run' link is provided for each script listed on the page above. Using the 'Run' link, you can conduct test runs of your scripts. When you click on the 'Run' link, you will be presented with another screen where a schema from the Datastore may be selected against which execute the script. This allows the IEG Engine know the structure and types of the data you intend to use when running the script. Any data elements you wish to save/retrieve from the Datastore as part of your script must be defined in this schema. If an appropriate schema is not available in the list, you should use the Datastore administration screens to upload one. Once you choose the appropriate schema, click on the 'run script' link to invoke the IEG Player to run your script.
