What you do is check to see if you have any input, if not then display the form, if you do then validate the input and skip the display. > 2) I have a drop down menu on one of my form fields.

If you want the text box to appear immediately then no, you'll need JavaScript. If you're ok with the user hitting submit and being re-desplayed the same page, this time with the text box showing, then that is trivial in php. You can use the same process as the validation in (1) above. Regards, Ozz.
