I took your advice and added 'i', it works now. Thank you.

I have added:

jcbSizes = new JComboBox();

The symbol above the ^ is the . between 'jtfDetails' and 'setVerticalAlignment'. Yes it is spelt correctly.

I'm trying to write a GUI that has 2 JPanels, the left panel with an image and JLabel below it, and the right one with a scrollable JTextArea. For whatever reason the JTextArea isn't showing up.

I've finally figured it out. What a silly mistake to make! Thanks man.

So one of my JPanels, JButtons or JLabels isn't correct?
