Email field size

Hi,
I have installed your plugin File Upload and I included 2 additionnal data fields (email and message). My only problem is that the fields are not wide enough, so a part of the text is cut . And when I try to enter an email in the field, it is barely visible (same for the message field).

Can you help me with that ?

Thanks
