last div falls down

[gambit_1607]

hi

i'm using ie6 and this is my site's code

<div id="content-area"> 
 
            
            <div class="panel-display panel-1col clear-block" id="welcome"> 
  <div class="panel-panel panel-col"> 
    <div><div class="panel-pane pane-custom pane-1" > 
  
  
  
  <div class="pane-content"> 
    <div class="welcome_message"><br /> 
    <h3><img src="sites/all/themes/yghhzen/css/images/helpingpeoplehelpthemselves.png" alt="Helping people help themselves."/></h3><br />

</div>  </div> 
 
  
  </div> 
</div> 
  </div> 
</div> 
 
        </div>

and the related CSS code

.grid {
    width: 92%;
    margin: -15px auto;
}

.grid-m1 {
  float: left;
  height: 1px;
}

.grid-c1 {
  float: left;
  width: 20%;
  /*border-bottom-style: dotted;
  border-bottom-color: #666;
  border-bottom-width: 1px;*/
  /*padding: 10px;*/
}

.grid-m2 {
  float: left;
  height: 1px;
}

.grid-c2 {
  float: left;
  width: 20%;
  /*border-bottom-style: dotted;
  border-bottom-color: #666;
  border-bottom-width: 1px;*/
  /*padding: 10px;*/
}

.grid-m3 {
  float: left;
  /*width: 2%;*/
  height: 1px;
}

.grid-c3 {
  float: left;
  width: 20%;
  /*padding: 10px;*/
}


.grid-m4 {
  float: left;
  /*width: 2%;*/
  height: 1px;
}

.grid-c4 {
  float: left;
  width: 20%;
  /*padding: 10px;*/
}

.grid-m5 {
  float: left;
  /*width: 2%;*/
  height: 1px;
}

.grid-c5 {
  float: left;
  width: 20%;
  /*padding: 10px;*/
}

when i resize the screen to a smaller width the last div - grid-c5 falls down. and everything else (grid-c1 - grid-c4) stay together in a straight alignment. i want the last div to not fall down and stay in a straight alignment like the rest of the divs

Make sure that the combined widths aren't exceeding their container, then check the margin and padding.
