I get this error Error: Expression expected.

This the element from the website :
1

<a href="javascript:void(0);" onclick="likepage('112581','ImMrClassy');" class="followbutton">Subscribe</a>

And this the code for thing I am trying to build :
1

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
2
       Button3_Click (Class="yt-subscription-button subscription-button-with-recommended-channels yt-uix-button yt-uix-button-subscribe-branded" data-subscription-feature="channels3")
3
    End Sub

And this is the error I get: Expression expected.
