I got a problem. My form Validation isn’t working. Actually to be more accurate, the chEmail function works but I also need Flash to check the input fields “first” and “last” to make sure something is entered in there? Am I missing something here or done something wrong? Thanks peeps

Here’s the code related to the validation

function ckName(){  
if (formData.first == “”){  
errBox.setMessage(“Oop’s, you forgot to fill in your first name”);  
return false; }  
else {  
return true};  
}

function ckName(){  
if (formData.last == “”){  
errBox.setMessage(“Oop’s, you forgot to fill in your last name”);  
return false; }  
else {  
return true};  
}

function ckEmail(){  
if(formData.submit\_by == “”){  
errBox.setMessage(“You Must Fill In Your Email Address”);  
return false;}  
else{  
if(formData.submit\_by.indexOf(".",0)==-1 || formData.submit\_by.indexOf("@",0)==-1){  
errBox.setMessage(“Your Email Address Is Not In Correct Form”);  
return false;}  
else{  
return true;}  
}

}

Don’t know if this well help, but instead of saying formData.first == “”, you could try

```auto

if(formData.first){
     the good stuff
}else{
     the bad stuff (error message)
}

```

Saying if(formData.first) will ask if there is anything there (same as nonzero).
