Okay, see this. It is not working.

Whereas, this is working.

They are the same but performing different tasks.

Oga! getElementById will only pick one tag.

Use getElementsByClassName to get all the inputs in first picture.

Advice.

Look into let and const keywords.

Try to know about code indentation.

I used notepad as text editor, reason why the code is not well indented

Sublime text is only 10mb.

Coding with notepad is torture.

For the checkColours function, you used getElementbyID but you are getting the name instead.

you did not add value attribute to them
e.g

<input type="radio" name="colours" id="purple" value="purple" > Purple

Obviously, this code won't work.
Your issues;
1. You're getting element by id but you're putting name,
2. getElementById does not return an array. So therefore, your for loop won't work and,
3. Your inputs does not have values

Thank you very much. I have been able to do it with your help. It was basically the omission of the semi colon to signal the end of each line that was the issue I guess!

Thank you, sir.

These days, semicolons are optional in Javascript.

Try to break your code into multiple lines though.
It's easier to read that way.
