Change this:

<input name="keywords" type="integer" class="searchinputbox" id="keywords" value="Find Products" size="15">&nbsp;&nbsp;&nbsp;

to

<input name="keywords" type="integer" class="searchinputbox" id="keywords" value="Find Products" size="15" onclick="javascript:this.value="";">&nbsp;&nbsp;&nbsp;

This doesn't cater for uses tabbing into the box though.

<input name="keywords" type="integer" class="searchinputbox" id="keywords" value="Find Products" size="15" onclick="clearField(this)" onfocus="clearField(this)">

<script>
  function clearField(this)
  {
      if (this.value == "Find Products")
      {
          this.value = "";
      }
  }
</script>


or you can simply try placeholder

<input name="keywords" type="integer" class="searchinputbox" id="keywords" placeholder="Find Products" size="15" onclick="" onfocus="">

just going to add tiny change to gurvinders solution, the use of defaultValue is nicer than having to use the physical string to compare against.
<input name="keywords" type="integer" class="searchinputbox" id="keywords" value="Find Products" size="15" onclick="clearField(this)" onfocus="clearField(this)">
<script type="text/javascript">
  function clearField(x){	  
      if(x.value==x.defaultValue){x.value="";}
  }
</script>
