HOw to hide a span in vb.net from code behind

Question

<CB:CBLocalizedLiteral ID="litTip" runat="server" LocalizationID="litTip" Text="Key Skills: (Click on a skill not to display it in the ad)"></CB:CBLocalizedLiteral></span>

 

This is my html

 

I declare it as ==      Public SpanSkills As HtmlGenericControl     in code 

 

If SettingControlAB.GetBoolean(oNeo, "bDisplaySkills", oNeo.MyLocale.HostSiteEnum) Then

SpanSkills.Visible = False

End If

 

  

its comming inside the flag and 

It is flag protected but its not working and the value still showing as visible when i debug .
