You'd change these two input tags:

<input class="name" type="text" value="Enter your name" onfocus="if(this.value==this.defaultValue)this.value='';" onblur="if(this.value=='')this.value=this.defaultValue;" tabindex="500" tabindex="900" />

<input class="email" type="text" value="Enter your email" onfocus="if(this.value==this.defaultValue)this.value='';" onblur="if(this.value=='')this.value=this.defaultValue;" tabindex="901" />

to look like this:

<input name="name" class="name" type="text" value="Enter your name" onfocus="if(this.value==this.defaultValue)this.value='';" onblur="if(this.value=='')this.value=this.defaultValue;" tabindex="500" tabindex="900" />

<input name="email" class="email" type="text" value="Enter your email" onfocus="if(this.value==this.defaultValue)this.value='';" onblur="if(this.value=='')this.value=this.defaultValue;" tabindex="901" />
