hi again! I just answered your other question and i think the similar problem is happening on this one! You have input set to 100%, which takes up the entire width and pushes the text down to the next line.
You might want to differentiate the different types of inputs in the CSS instead of having them all be the same width (i.e. have your text input as one class, and radio button as a different class, which you already do have as bouton).
Also some other notes: id attributes should be unique. if you want to use the same designation for more than one item, you can use classes.
Let me know if this helps! good luck
