Search box not working

Hi,

My blog is at https://nelmitravel.com and I am using an Evolution theme. I cannot get the Search box Widget to work. I disabled the standard widget that came with the theme and then uploaded a simple search button:

<div class=”searchform”>
<form method=”get” id=”searchform” action=”/search”>
<table width=”100%”>
<tr>
<td><input type=”text” style=”width:98%;padding:2px;” value=”Search this blog…” onfocus=”if (this.value == "Search this blog…") {this.value = ""}” onblur=”if (this.value == "") {this.value = "Search this blog…";}” name=”q” id=”sbox” class=”sbox”></td>
<td width=”75px”><input type=”button” Value=”Search” id=”sbutton” class=”sbutton” alt=””></td>
</tr>
</table>
</form>
</div>

Still no luck. What is going wrong and can somebody please help me to get this fixed?

Thank you!
Nelieta
