+      <para>To work with this layer, click the event layer icon on the map toolbar and select "Edit
+        layer". Select a program and then select a program stage. If there is only one stage
+        available for the selected program, the stage will be automatically selected. A list of data
+        elements and attributes will appear in the "Available data elements" panel. You are free to

+        or by start typing directly in the box to filter for options.</para>

+        using the "start date" and "end date" date pickers under the "Periods" section, as well as
+        the organisation units to include in the query under the "Organisation units"
