ok hier mal ein grober ausschnitt des problems:

  
<FORM method="post" action="index.php?section=Auftragen&do=senden">  
<TABLE border="0" align="center" width="550px" cellpadding="0" cellspacing="0">  
 <TR>  
  <TD>*</TD>  
  <TD>VORNAME:</TD>  
  <TD><INPUT type="text" size="25" name="vorname" onchange="vorname()"></TD>  
 </TR>  
 <TR>  
  <TD></TD>  
  <TD>AUSGEFÜLLTE PFLICHTFELDER:</TD>  
  <TD><DIV style="height:20px;width:170px; float:left;"><INPUT type="text"  name="fb" style="height:20px; width:<?php if(isset($_GET['paket']) AND isset($paket[$_GET['paket']])) { echo '12.5%'; } else { echo '0%'; }?>; background-Color:red; border:0px;" readonly></DIV><INPUT type="text" style="color:red;" value="<?php if(isset($_GET['paket']) AND isset($paket[$_GET['paket']])) { echo '12.5%'; } else { echo '0%'; }?>" name="fb" size="5" style="border:0px;float:left; height:20px;background:transparent;color:blue;" readonly></TD>  
 </TR>  
    <TR>  
     <TD></TD>  
        <TD><INPUT type="submit" value="SENDEN" name="senden" onMouseOver="senden()"/></TD>  
        <TD></TD>  
    </TR>  
</TABLE>  
</FORM>  

und hier die JS:

  
function vorname() {  
 if(document.getElementsByName("vorname")[0].value != "" && vn == 0) {  
  n = n + 1;  
  vn = 1;  
 } else if(document.getElementsByName("vorname")[0].value == "" && vn == 1) {  
  n = n - 1;  
  vn = 0;  
 }  
 document.getElementsByName("fb")[0].style.width = n*12.5 + "%";  
 document.getElementsByName("fb")[1].value = n*12.5 + "%";  
 if(document.getElementsByName("fb")[0].style.width == "0%") {  
  document.getElementsByName("fb")[0].style.backgroundColor = "red";  
  document.getElementsByName("fb")[1].style.color = "red";  
 } else if(document.getElementsByName("fb")[0].style.width == "50%") {  
  document.getElementsByName("fb")[0].style.backgroundColor = "orange";  
  document.getElementsByName("fb")[1].style.color = "orange";  
 } else if(document.getElementsByName("fb")[0].style.width == "75%") {  
  document.getElementsByName("fb")[0].style.backgroundColor = "#0000FF";  
  document.getElementsByName("fb")[1].style.color = "#0000FF";  
 } else if(document.getElementsByName("fb")[0].style.width == "100%") {  
  document.getElementsByName("fb")[0].style.backgroundColor = "green";  
  document.getElementsByName("fb")[1].style.color = "green";  
 }  
}  
  
function senden() {  
 if(document.getElementsByName("fb")[0].style.width != "100%") {  
  alert("SIE HABEN NOCH NICHT ALLE PFLICHTFELDER AUSGEFÜLLT");  
 }  
}
