Question

I’m making a form and want something to happen when just a certain part of the form has been completed. I’ve got some checkboxes, a dropdown menu, and three read-only text fields. I need something to pop up when the checkboxes and dropdown fields have been populated, but have no idea how to do this. I tried putting a form within a form, but after that failed and I later read up on the matter, I found that to be impractical. Anyhow, here’s my code for the form:

<form action="http://siedb1.sys.virginia.edu/~jhr3ct/Code/Reserve%20Confirmation.php">
        Facility: <input type="checkbox" name="facility" value="AFC">AFC
        <input type="checkbox" name="facility" value="Memorial Gym">Memorial Gym
        <input type="checkbox" name="facility" value="Slaughter">Slaughter
        <input type="checkbox" name="facility" value="North Grounds">North Grounds<br>
        Type of Room/Court: 
        <select>
            <option value="default">Choose room...</option>
            <option value="squash">Squash</option>
            <option value="handball">Handball</option>
            <option value="racquetball">Racquetball</option>
            <option value="multipurpose">Multipurpose</option>
        </select><br>
        Room: <input type="text" name="start" readonly="readonly"><br>
        Start Time: <input type="text" name="start" readonly="readonly"><br>
        End Time: <input type="text" name="end" readonly="readonly"><br><br>
        <input id="submit" type="submit" value="Submit">
    </form>

Thanks for the help!
