Multiple if statements in validateLine function

I am trying to create a script to validate line items based on the selection of a custom field on a sales order record. So I need to script to run through each selection item and check to see if the items noted in the script have been added to the order. If so, I wish to present a message. If item is not on order then I wish to move on to the next if statement. During testing I am finding that both alerts are being displayed. What am I missing? Here is my script:


function validateLine_rec() {

var stRecord = nlapiGetRecordType();
