Drop down on PHP form only working on first 2 items

Question

I've made a landing page with form. And made 4 options from drop down select. The form send fine, but for some reason, only the 2 values of $499 and $999 work, the $1999 and $4999 don't work. I must be missing something? The from works and sends fine, I receive it and the info is there except for the 2 last options on drop down...

Code is here:

 <select name="budget_selection" class="form-style-10-drop-down" required='required'>
                                    <option value="">- select -</option>
                                     <option value="$499">$499</option>
                                    <option value="$999">$999</option>
                                    <option value="$499">$1999</option>
                                    <option value="$999">$4999+</option>
                                </select>

Answer 1

You repeated the same values

<option value="$499">$1999</option>
<option value="$999">$4999+</option>

It should be

<option value="$1999">$1999</option>
<option value="$4999+">$4999+</option>

Answer 2

Your option values have the same values as the first two.
