Re: How to change value of input on form from iframe?

Hi! Never worked with IFRAMEs nor sure how i can access their forms with JavaScript? maybe it's like: framename.document.formane.field ? anyway.... As i understand: * Main form have Combo1 that when it's selection is changed then IFRAME.Combo2 is rebuilt right? I see you set your frame source to myframe.php?id=id_from_combo1 Now when the main page is reloaded you must have a variable called $id too, So basically as the Combo1 have <option> and you need to position the last one before the form was posted then make use again from the $id variable. like for example: after the main form has been loaded, generate this script: <script> document.mainform.combo1.selectedIndex = <?=$id?>; </script> This was an example.... Hope i help a little. -elias "Dezider Góra" <gora@wittmann.sk> wrote in message news:3AFFD110.CD569924@wittmann.sk... > I'm having a big problem. > I've created "bound" combo's page, that works.
