One topic would’ve been enough..
But yea, you just change it and look at the page, select it from the dropbox and submit the form.
You don’t have to press ‘enter’ after changing it just make sure that ‘Ronald’ is in the box. (Not ronaldo!)
You used inspect elements? So you’ve got the script there and changed a users name to ‘Ronald’? Then you can just press ‘enter’ or click somewhere else in the source code and Ronald should be in the dropdown.
If you somehow can’t do that, you still can create your own HTML file and try it this way. Might be better for you..
Hope I didn’t tell to much, kind of sounds like a Tutorial..
