Example 3a: Chemical elements II

This example is functionally identical to example 3, but here the hidden iframe and trace log are made visible to help with debugging. This is accomplished by adding the trace attribute to the <cf_srs> tag.

You'll note that several events appear in the trace log when the page first loads. Some of these events are associated with populating the select box of authors.

Note also that the trace log is read from bottom to top: the newest event appears first.
