Hi Scott,

Welcome - and I hope you find your dip into perl an enjoyable experience!

The correct way to mark an option as selected is:
    $field->default( $value );

This will automatically add selected="selected" to the option item
matching $value.

default() is also the correct way to do this for all fields, rather
than using attributes().

I'll make myself a note to look at the docs, and try to make this more clear.

Cheers,
Carl
