Hallo All,

I have masterdetail relationship between two objects quotes(parent) and quotelineitems(child)

REQUIREMENT: i am trying to create a trigger to update a field in quotes based on field condition in quotelineitems

NOTE: quotelineitems(child) also have lookup relationship with product(parent)

CODE:

trigger test2 on Quote (before insert) 
{
    if(trigger.isinsert && trigger.isbefore)
    {
        for(Quote q1:trigger.new)
        {
            list<quotelineitem> qli  = [select id,Produktname__c,Gegenkonto_AGBP__c from quotelineitem where Gegenkonto_AGBP__c = '84000' or Gegenkonto_AGBP__c = '84001'];
            list<quote> q = [select id,Name,Angebotsinhalt__c from quote where recordtype.name = 'angebot'];
            if(qli.Gegenkonto_AGBP__c == '84000')
            {
                q.Angebotsinhalt__c = qli.Produktname__c;
            } 
            else if(qli.Gegenkonto_AGBP__c == '84001')
            {
               q.Angebotsinhalt__c = 'produktion'; 
            }
            else
            {
                q.Angebotsinhalt__c = 'sonstiges';
            }
        }
    }
}

ERRORS:

Variable does not exist: Gegenkonto_AGBP__c
Variable does not exist: Produktname__c
Variable does not exist: Angebotsinhalt__c
Variable does not exist: Gegenkonto_AGBP__c
Variable does not exist: Angebotsinhalt__c
Variable does not exist: Angebotsinhalt__c


but when i look at the objects metadata i have all the above mentioned fields but when i try to code i am getting the above errors.

quote object fields:
Angebotsinhalt__c(text field)

quotelineitem fields:
Produktname__c(text field)
Gegenkonto_AGBP__c(picklist field)

Can someone please let me know at which part of the code i have gone wrong so that i can rectify?

Thanks for your help!
