Is there a way to make a text box a required item to be filled out?

  Just add the word "required" to the input box. <input type="text" required ... >  

Hey Ray,
The code that you told me to input isn't working for me. I must be missing something, eh? Here's what I input:

<input type="text" required name="eCart1_5_Name_Add" value="First and Last Name" />
<input type="text" required name="eCart1_5_Grand_Add" value="Grand" />
<input type="text" required name="eCart1_5_PupTentName_Add" value="Pup Tent Name" />
<input type="text" required name="eCart1_5_Description_Add" value="VFW LM Number" />
<input type="text" required name="eCart1_5_Title_Add" value="Date of Birth" />
<input type="text" required name="eCart1_5_CootieNumber_Add" value="Annual Card Number" />

I also tried it this way by checking the "Required" box in my "Properties" panel and it changed to this:

<input name="eCart1_5_Name_Add" type="text" required="required" value="First and Last Name" />
<input name="eCart1_5_Grand_Add" type="text" required="required" value="Grand" />
<input name="eCart1_5_PupTentName_Add" type="text" required="required" value="Pup Tent Name" />
<input name="eCart1_5_Description_Add" type="text" required="required" value="VFW LM Number" />
<input name="eCart1_5_Title_Add" type="text" required="required" value="Date of Birth" />
<input name="eCart1_5_CootieNumber_Add" type="text" required="required" value="Annual Card Number" />

The "Add to Cart" button still lets me go to the checkout page. Thanks again for your help Brother!
All the best,
