I am having an issue passing an input field from a Visualforce page to new inserted records. The field I am trying to pass is 'Remarks_Special_Instructions__c' but when I put info in there it is not saving into the newly created records. I have tried a few different ways but no luck on any front. What are my issues? Thanks in advance!

Apex: 

public with sharing class quoteAssociatedSiteExtension {

	//Our collection of the class/wrapper objects cContact 
	public Quote theQuote {get; set;}
    public List<assLoc> assLocList {get; set;}
    
    public quoteAssociatedSiteExtension(ApexPages.StandardController controller) { 

        String quoteId = ApexPages.currentPage().getParameters().get('quoteId');
		theQuote = [select Id, AccountId from Quote where Id =:quoteId limit 1];
    }

	//This method uses a simple SOQL query to return a List of Contacts
	public List<assLoc> getAssLoc() {
		if(assLocList == null) {
			assLocList = new List<assLoc>();
			for(Site__c s: [select Id, Name, Account__r.Id, City__c, Country__c,Order_Master_ID__c, Order_Master_Link__c, Site_ID__c, Site_Main_Phone__c, State__c, Street__c, Zip__c
                            from Site__c 
                            where Account__r.Id=:theQuote.AccountId
                           ]) {
				// As each contact is processed we create a new cContact object and add it to the contactList
				assLocList.add(new assLoc(s));
			}
		}
		return assLocList;
	}
    
	public PageReference processSelected() {

                //We create a new list of Contacts that we be populated only with Contacts if they are selected
		List<Site__c> selectedAssociatedLocations = new List<Site__c>();

		//We will cycle through our list of cContacts and will check to see if the selected property is set to true, if it is we add the Contact to the selectedContacts list
		for(assLoc aLoc: getAssLoc()) {
			if(aLoc.selected == true) {
				selectedAssociatedLocations.add(aLoc.st);
			}
		}

		// Now we have our list of selected contacts and can perform any type of logic we want, sending emails, updating a field on the Contact, etc
		List<Associated_Location__c> nmal = new List<Associated_Location__c>();
        for(Site__c al: selectedAssociatedLocations) {          
            Associated_Location__c nal = new Associated_Location__c();
            nal.Site__c = al.Id;
            nal.Quote__c = theQuote.Id;
            nmal.add(nal);
		}
		insert nmal; 
        return new PageReference('/'+ApexPages.currentPage().getParameters().get('quoteId'));
	}


	// This is our wrapper/container class. A container class is a class, a data structure, or an abstract data type whose instances are collections of other objects. In this example a wrapper class contains both the standard salesforce object Contact and a Boolean value
	public class assLoc {
		public Associated_Location__c ac {get; set;}
        public Site__c st {get; set;}
        public Quote qt {get; set;}
		public Boolean selected {get; set;}

		//This is the contructor method. When we create a new cContact object we pass a Contact that is set to the con property. We also set the selected value to false
		public assLoc(Associated_Location__c a) {
			ac = a;
			selected = false;
		}        
        
        public assLoc(Site__c s) {
			st = s;
			selected = false;
		}
        
		public assLoc(Quote q) {
			qt = q;
			selected = false;
		}        
	}
}
