Input field font problems

When I preview my form I can use upper and lower case letters. When I add the form to a page, all of my letter are displaying upper case. I can't enter upper and lower case letters to the input fields, however the notification email displays the correct upper and lower case lettering.

Help and thanks

This text-transform from your theme's stylesheet is causing it:

[css]
input, select, textarea {
vertical-align: middle;
font-family: Arial, Helvetica, Sans-Serif;
font-style: normal;
font-weight: bold;
font-size: 11px;
text-transform: uppercase;
}

Try placing this into the stylesheet:

[css]
.gform_wrapper input[type="text"], .gform_wrapper input[type="url"], .gform_wrapper input[type="email"], .gform_wrapper input[type="tel"], .gform_wrapper input[type="number"], .gform_wrapper input[type="password"], .gform_wrapper textarea, .gform_wrapper select {
text-transform: none;
}

Right on, glad to help!
