How to use "HTML form target self" ? : I am new to HTML and need to complete a simple task.

I have a database with some numbers assigned to a fake account (PHP).
I try to contact the database (with success) and get the right result from the form. 

My issue is that the form result open a new page and display there...
I would really like the result to be displayed IN the module I use to send the form OR anywhere else on the same page I used to send the form.

Here is my code:

    <!DOCTYPE html>
    <html>
    <body>
    
    <form 
        method="post"
        action="http://ggdbase.dx.am/impulseGetInfo.php" 
        target="_self">
        
         Account name:<br>
         <input type="text" name="name" value="derps">
         <br>
         <input type="submit" value="Click To Load Account Info">
    </form> 
    
    </body>
    </html>

[This is what the module look like (on Enjin.com)][1]

[This is what I get when clicking the button][2]

I did try replacing '_self' with '_blank' or parent and all the other options I could find but none of them gave me a different result :S

**Also , could it be caused by the Enjin system itself ?

If anyone have a clue how I can fix this, I cant wait to get your feedback !
