hi all, i'm confused with this. i'm developing a form by getting data from mysql database. i have two list/menu fields. first field displays the main categories from the database. and the second one displays the subcategories of the selected category from first menu. up this every thing is fine. after selecting the category wrote a function to submit the form. and after reloading the category should be selected automatically from the following code written after while loop. <? if($_POST['cat']!="") { ?> <script language="javascript"> var catg=<? echo $_POST['cat'] ?>; var i; for(i=1;i<=document.form1.cat.options.length;i++) { if(document.form1.cat.options.value==catg) { document.form1.cat.options.selected=true; } } </script> <? } ?> it was working nice for this. but after selecting subcategory also submitting the form and after reloading subcategory field also should be selected automatically same as the category field.but here some problem is arising. it selects the default field from the list.i wrote similar code as for first one. i'm giving the second one's code also. <? if($_POST[subcat]!="") { echo "subcat=".$_POST[subcat]; ?> <script language="javascript"> var subcatg=<? echo $_POST[subcat] ?>; for(i=1;i<=document.form1.subcat.options.length;i++) { if(document.form1.subcat.options.value==subcatg ) { document.form1.subcat.options.selected=true; } } </script> <? } ?> please anyone help me. thanks in advance.

thanks but it was solved a little bit. but here is some more.i have a check box given value 'y' when checked. but it was taking 'y' every time means either it is checked or not.to give you the clearence i'm giving you the short form of the code. the form code is here follows............. <form name=form1> <select name='topic'> <option value=''>SELECT TOPIC</option> //here i have displayed the topics from database using while loop.they were displayed correctly </select> <input name=newtopic type='text' size='50'> <input name=category type='text' size='50'> <input name="main" type="checkbox" id="main" value="y" /> </form> // and on submit form was validated so that when ever the 'category' is not given and 'main' was selected then 'topic' or 'newtopic' should not be selected .and there i gave an alert. due to main value displying 'y' all the time, it was giving alert even when the category is also given.this is the problem.
