I know how to pass the variables, and I know how to do this in javascript ... but not .net.<BR><BR>Basically, I have one main page with two embedded IFRAMES (call them ILeft and IRight).<BR>I would like to ... make a selection in ILeft, and have it change the content in IRight. I have an alternate work around for this, but this would be the optimal way for me to code this.<BR><BR>So, basically, my question is how do I identify the IRight IFRAME from the ILeft IFrame (both of which are in a parent window), and pass it my variables?<BR><BR>Thanks for any help,<BR><BR>Danny
