I would like to be able to dynamically resize the height of the iframe based on the height of the source document. I have access to both the source document and the actually document. I need for it to work correctly in Mozilla, Netscape, and IE. The width of the iframe will always be 540, no matter the width of the source. The height is the only variable that will change. The source page is a calendar and will be dynamically updated as events are entered the height of the calendar page will increase, which is why the height of the iframe will increase as well. I hope that makes sense, if not let me know. Thanks for your help.
