select list forms and text boxes....

[Dutch_MaFia-boy]

I have a list box and a text box. The list box has a blank entry by default <selected> and the text box has is blank as well.

I want to give an error if box boxes have a value in them - I want one of them to be blank while the other one has a value in it...

How would I go about doing this??

Thanks.

your better off with javascript on this, try this for effect:

function checkFields()
{
var myForm = document.forms[0];
if ((myForm.txtField.value!='') && (myForm.lstbox.value !=''))
{
alert('Error Message');
return false;
}
return true;
}

just call this function on your on submit event.
here's an additional tip:
add this to your textbox:
onkeypress="javascript: document.forms[0].lstbox.value='';"
and inside your listbox:
onchange="javascript: document.forms[0].txtbox.value='';"

As you continue on, you'll find that this are pretty simple codes but hope it helps you today.
