Off Topic:
You really should use <label> tags with your form inputs; placeholder text is not enough.
Suppose a visitor is in the middle of completing your form, clicks into a field (so the placeholder text is removed) and then the phone rings, or somebody comes to the door. When they return to the form twenty minutes later, how are they to know what information is required in that field? There is no longer anything to tell them. (I speak from experience here; this has happened to me.)
Using labels is also important for accessibility for those using assistive technology.
