I have installed and setup Formbuilder and Captcha extension...

Formbuilder works well but captcha doesn't display an error message when you don't enter the correct characters...

It only displays the instruction message...

How can I make sure the error message is displayed if the captcha form is incorrectly filed...?

Try change module to CGBetterForms, in my opinion it's better solution.

Check your form template, and compare it against one of the default templates. It should and does work fine unless something has been changed.

Also make sure to inspect the output to make sure it's not an html or css issue hiding it.
