Compile Error: Invalid field Materials for SObject Materials_Junction__C

Hi All, 

I am hoping you can help me.

This is my Controller, however when i am saving i am getting the the following error message "Error: Compile Error: Invalid field Materials for SObject Materials_Junction__c at line 33 column 17"

i have looked through the relevant examples on wrapper classes however i am a now stuck. 

Really appreciated you help 

public with sharing class testWrapper
{
    public List<Materials__c> Materials {get;set;} 
    public List<materialWrapper> materialWrapperList {get;set;} 
    
    public testWrapper()
    {
        Materials = [select ID,name,Product__c, Item__c,Quanity__c, Active__c from Materials__c where Active__c =true limit 10];
        for(Materials__c obj : Materials)
        {
            materialWrapper tempObj= new materialWrapper();
            tempObj.recordId = obj.id;
            tempObj.name = obj.name;
            tempObj.product = obj.Product__c;
            tempObj.item = obj.Item__c;
            tempObj.quantity = obj.Quanity__c;
            tempObj.selectB = false;
            materialWrapperList.add(tempObj);
        }
    }

    //save method
    public void save()
    {
        list<Materials_Junction__c> recordToInsert = new list<Materials_Junction__c>();
        
        for(materialWrapper obj : materialWrapperList)
        {
            if(obj.selectB == true)
            {
                Materials_Junction__c temp = new Materials_Junction__c();
                temp.sales_and_marketing__c = '01I20000000rV6V';
                temp.Materials= obj.recordIdId;
                temp.quantity = obj.quantity; 
            }
            recordToInsert.add(obj);
        }
        insert recordToInsert;
    }
    
    
    public class materialWrapper

modify the above lines.please use API name of fields not labels

HI Ram, 

I think get the following error "Compile Error: Incompatible element type testWrapper.materialWrapper for collection of Materials_Junction__c at line 36 column 1"

Hi,

Could you change the below line and try once.
 
​48        public Number quantity {get; set;}

 
Daniel MasonDaniel Mason
That gives me "Compile Error: Invalid type: Number at line 48 column 16" . quanitiy on the Materials_Junction__c has the following data type Number(18, 0)

Hi ,

 

I have made the following edits and i can now save the apex class 

 

Line 36 :

recordToInsert.add(obj);

I then changed the following 

for(materialWrapper obj : materialWrapperList)
        {
            if(obj.selectB == true)
            {
                Materials_Junction__c temp = new Materials_Junction__c();
                temp.sales_and_marketing__c = '01I20000000rV6V';
                temp.Materials= obj.recordIdId;
                temp.quantity = obj.quantity; 
            }
            recordToInsert.add(obj);
        }
        insert recordToInsert;
    }

To 
for(materialWrapper obj : materialWrapperList)
        {
         Materials_Junction__c temp ;
            if(obj.selectB == true)
            {
                temp = new Materials_Junction__c();
                temp.sales_and_marketing__c = '01I20000000rV6V';
                temp.Materials__C= obj.recordId;
                temp.quantity__C = obj.quantity; 
            }
            recordToInsert.add(temp);
        }
