Hi, In your javascript try field1=Number(thisform.field1.value) etc... Cheers Simon -----Original Message----- From: Shahmat Dahlan [mailto:shahmatd@sains.com.my] Sent: 11 October 2002 11:35 To: php-db@lists.php.net Subject: Javascript My question might have anything to do with PHP but I have the following scenario: Say I have four fields field1 : XXXXXXXXXXXX field2 : XXXXXXXXXXXX field3 : XXXXXXXXXXXX field4 : XXXXXXXXXXXX And a total sum field, which is a total sum of the value of the expression, totalsum = field1 + field2 + field3 + field4 Total sum : XXXXXXXXXXX You would need to use Javascript to extract the value of field1, field2, field3, field4, initiated by the Javascript onChange event. The HTML codes should look like this: <input type="text" name="field1" addChange="add();"> <input type="text" name="field2" addChange="add();"> <input type="text" name="field3" addChange="add();"> <input type="text" name="field4" addChange="add();"> <input type="text" name="totalsum"> So the add function snippet that I have: function add() { var thisform=document.forms[0]; var field1=thisform.field1.value; var field2=thisform.field2.value; var field3=thisform.field3.value; var field4=thisform.field4.value; var totalqty=field1+field2+field3+field4; thisform.totalsum.value=totalqty; } But all I got is a NaN which means Not A Number. I understand that you solve this by using the parseInt Javascript function. But still all i get is a NaN value. Would appreciate if someone could help me out on this.
