[jQuery] resize iframe to fit contents

[kevind]

hi,

i have an iframe on page to hold record editing form - the form
presented in the frame needs to   be different sizes depending on the
form size

i want the page called to resize the frame but, i can't figure out how
to refer to it from the page loaded in the iframe

parent().$("#myiframe").height( $("#formcontentwrapper").height() ) ;

any help appreciated
