I am trying to use this form to display tables in my database. I am unsure what I am doing wrong. I swapped the positions of the "form" and "select" tags assuming that was the fix. But everytime anything from the drop-down is selected the page simple reloads with my normal database creation. As you can see I am populating my tables within php, my only issue is when I try and put that information into an HTML form it doesn't work. I can send you examples of what I mean it this will help, but I assume you get what I am trying to do.
<!-- Use JavaScript to automatically submit the selection -->
<select name="lstDisplay" onchange="this.form.submit()">
<option value="null">Select an item</option>
<option value="concert">Concert</option>
<option value="attendee">Atendee</option>
<option value="venue">Venue</option>
</select>
<!-- set up alternative button in case JavaScript is not active -->
<noscript>
<input type="submit" name="btnSubmit" value="View the list" />
<br /><br />
</noscript>
<!-- Use a hidden field to tell server if return visitor -->
<input type="hidden" name="hidIsReturning" value="true" />
</form>
