Question

cant seem to make this work. i want to go back to the form after submitting. but it just displays

**Object not found!**

The requested URL was not found on this server. The link on the referring page seems to be wrong or outdated. Please inform the author of that page about the error.

If you think this is a server error, please contact the webmaster.

**Error 404**

localhost

and also the alert does not pop up. or it will not pop up because there is an error?

my php

if (mysqli_query($con,$sql))
    {
        ?><script>
            alert('Saved Successfully!');
            window.location = ".../cnc/makerForm.php";
        </script><?php
    }

my html

<div class="w3-border">
    <h6 class = "w3-grey trbl-padding-5 trbl-margin">Maker</h6>
    <a class="w3-btn-floating w3-pale-yellow" onclick="return toggleMakerBox('iframe_makerForm')">+</a>
    <iframe height="400px" width="100%" src="makerForm.php" style="display:none;" name="iframe_makerForm" id="iframe_makerForm"></iframe>
</div>

This error means that the file you are targetting does not exist. As pointed out in the comment, it is most probably because you write ... instead .. in the redirect path declaration window.location = ".../cnc/makerForm.php";.
