Hi there,
I am new to freeform and EE. The problem I faced may be very basic but I really need some one to guide. I have used a captcha field in my form. When the captcha fields doesn’t match I get a error message “The captcha word you submitted is incorrect. Please go back and try again”. I want to change the design of this page so that this page would look like part of my website. Please help.

I believe that would be running off of the ExpressionEngine standard User Message Template:
CP Home › Admin › Specialty Templates › User Message Template

You can customize it there, however, as a warning, that template is used for MANY EE errors/success pages, so you’ll have to keep that in mind.

Your other option would be to implement Javascript with Solspace’s onSubmit extension.

Thanks Pie-Man. I will surely look into it.
I have aother query. Suppose on my site there is a registration form and I want to store the registerd users details in my database table named tbl_registeruses. What procedue I should follow? Thanks in advance.

You’d want to write an extension that executes on one of the Freeform extension hooks to do that additional insert.
