[Plugin: Fast Secure Contact Form] Message Font Too Small?

Hi,
I am not sure why the font size inside of the “Message” text field is smaller than the rest of my input text fields but I would greatly appreciate any help you could give me.

The contact form is located at: http://poquosonplumber.com/contact-us/

I did try to use the css inside the form setup but was unable to find a particular line for just the message box. I increased the size to all the fields to “medium” (which helped made the “message” text readable but it is still smaller than the others because they all increased in size too.)

Thank you!
