hi ...

in your attached code you have:

[CODE=asp]<input type="text" name="purpose" style="visibili ty:hidden; width:400px" maxlength="150" value=<%=porpos e%>>[/CODE]
add an id-attribute since the toggle-function relies on it ...

kind regards

Hi gits
Thanks for your kind time to time guidance
this code work fine

[CODE=javascript]
function toggle_state(ob j) {
// here we check the value of your select-box
//var val = obj.value == 1;

if (obj.value == 1)
{
val=1;
}
else
{
val=0;
}

var input_node = document.getEle mentById('purpo se');

input_node.styl e.visibility = val ? 'hidden' : 'visible';

}
</script>[/CODE]

your adaption is definitly equivalent to the simple one line that you have 'outcommented' ... this couldn't have made a problem ... simply produces more lines of code and worse performance since 0 and 1 has to evaled to false/true in our assignment later on ... so it has to work with the

[CODE=javascript]var val = obj.value == 1;
[/CODE]
too?

kind regards
