W3 Validation Problem

[ilya Kraft]

Hi, tried to validate my website and came across several problems, some I understood, but the following one Is confusing to me.

Line 137, Column 139: Element input with attribute type whose value is button must have non-empty attribute value.

…7Bup%7D+likes% 2C+%7Bdown%7D+d islikes'/><input type='button' class='pulse_vo te_…

I don't understand what it wants from me...

Here is link to W3 page:

It's saying buttons need a [value] attribute.

<input type="button" value="Click Here" />
