Hi thanks for the quick reply.Anyway, this is how it is:1. On all my pages I have this form:<form name="frmMembers" action="login.html" method="post"><td width="39%"> <div> <p><nobr> <input type="text" name="email" size="10"><input type="hidden" name="r_email" value="Username"><input type="password" name="passed_password" size="10"><input type="hidden" name="r_passed_password" value="Account Password"><input type="submit" value="Login" name="btnSubmit"></nobr><nobr> </nobr></p></div></td></form>This will submit the username + password to a login.html page (which is a billing system). The user will automatically be logged in to the billing system.So the form works 100%.2. Rather than going this way (which gives me the billing system ugly html), in order to keep my site look (header, footer, color) I created a template which the body displays the real billig system login via:<iframe id="frame" name="frame" src="login.html" width="963" height="1100" border="0"></iframe>3. What I want to achieve is after the users type in username + password to be redirected to the template page which I created and passon the credentials on that page but to the Iframe bit.Here is the requested link:http://www.auswebserv.comyou can find in there the username and password form.http://www.auswebserv.com/billing.htmlthis is what I want to achieve - EXECEPT that users will not be promted by the login page for the billing system they will already be logged in.Should I post more code? But I dont think the rest is relevant as is HTML and nothing to do with m form and the iframe statement.Thanks for helping again.
