In meta code:

DO DBQUERY <fetch [list] with argument [which list] from the previuos form>

DO WRITE "<FORM ... etc, etc>"
DO WRITE " <SELECT ... etc, etc, blaha, blaha>
DO WHILE <not end of the [list]>
  DO WRITE " <OPTION VALUE=" + <your value for this [list].[element] +
">"
  DO WRITE " [list].[element]"
  DO WRITE " </OPTION>"
END WHILE
DO WRITE " </SELECT>"
DO WRITE "</FORM>"

And at last and most important:

WHILE (NOT <understand HTML>)
  GOTO http://www.w3.org/MarkUp/Guide/
END WHILE
IF (<still wants to learn more>)
  GOTO http://www.w3.org/MarkUp/Guide/Advanced.html
ELSE IF (<wants to read core specification>)
  GOTO http://www.w3.org/TR/html401/
ELSE IF NOT (<know how to program something>)
  <read Knut's handbook>
ELSE IF (NOT <problem still solved>)
  <then ask for help>
END IF
