[drupal-devel] problem with IE and form_group_collapse()

Hi, I have having a problem with tables in a collapsible group when using IE. if you use the following code when you try to expand the group under IE the the table does not appear. I do think that this is some that I have done because on the upload module the upload group works fine once it has files attached it works fine, but for some reason I cannot work out why it does not work. Can someone please shed some light. Here is some example code that I just put into a node with the PHP filter and it replicates the problem. <?php $header = array('col 1', 'col 2'); $rows[] = array('col 1', 'col 2'); $tbl = theme('table', $header, $rows); echo form_group_collapsible('test form', $tbl, TRUE); ?> Thanks in advance. Gordon.
