Hi,

I have  a javascript list button "Create Purchase order" on custom object Order_Lines__c(child object of Sales_Order__c) which creates a purchase order for the selected order lines.

The code goes like this :

{!REQUIRESCRIPT("/soap/ajax/13.0/connection.js")}


var records = {!GETRECORDIDS($ObjectType.Order_Line__c)};
var newRecords = [];

/*Ensure atleast one order line is selected*/

if (records[0] == null)
{
alert("Please select at least one Order Line")
}

/*Create a purchase order for the selected records*/
else
{
for (var n=0; n<records.length; n++) {
var c = new sforce.SObject("Order_line__c");
c.id = records[n];
newRecords.push(c);
}
result = sforce.connection.update(newRecords);
/*Open a new Purchase Order form and prepopulate with values*/

window.location.href ="/a0I/e?retURL=%2Fa0I%2Fo"+
"&CF00NR0000000cvG6={!Sales_Order__c.Name}"+
"&CF00NR0000000cvEt={!Sales_Order__c.Default_Warehouse__c}" +
"&00NR0000000cvEU={!Sales_Order__c.Order_Date__c}
}

This is working fine.
Now i want to add another validation:The field supplier__c on the order lines object must have the same value for the selected records.


I have tried adding the validation as follows:

{!REQUIRESCRIPT("/soap/ajax/13.0/connection.js")}

var records = {!GETRECORDIDS($ObjectType.Order_Line__c)};
var newRecords = [];
/*Check if records are selected*/
if (records[0] == null)
{
alert("Please select at least one Order Line");
}


 else{
          var myarray=new Array();
          for (var n=0; n<records.length; n++) {
var c = new sforce.SObject("Order_line__c");
c.id = records[n];
/*Copy the supplier field into an array for all the selected order lines*/
myarray[n]=c.supplier__c;
              }                                                             }
var t=array.length-1;
for (var d=0;d<t;d++)
{
if(array[d] <>array[d+1]){
alert("SOrry ,need same supplier for each order line");

}

else
{
/*Code for creating a new Purchase order*/
}
}

however this is not working and it gives a syntax error.

Please help with the syntax and the logic used  if its not ok.
