I don't understand whats wrong here: the first getrow in the second
foreach loop (after writing "<li>communities") fails:

foreach section_key { elearning communities garden } {
        ns_write "<li>$section_key"
        set selection [ns_db select $db "
        select one_line from bboard"]
        while { [ns_db getrow $db $selection] } {
        set_variables_after_query
        ns_write "<li>$one_line"
        }
}

Say the word if you want me to go elsewhere with tcl questions like
this - it will not be the last.
