Hi,

I need your help to write a trigger on Tasks which calculates the total Costs from all the SubTasks on a Project Stage
and update it in the Main task fields. I have an error when I try to save the trigger:
Compile Error: Loop with query must provide a statement

trigger IMSSumCostsOnTasks on TASKRAY__Project_Task__c (After insert, After Update) {
// TaskRay Project Task is a related Task object from TaskRay project object.
Set<Id> setTaskRayTaskIds=new Set<Id>();
For (TASKRAY__Project_Task__c c : trigger.new)
setTaskRayTaskIds.add(c.id);
//List of sub Tasks : Sub Tasks are those with empty value in Project stage
List<TASKRAY__Project_Task__c>ListTasks1 =[SELECT TASKRAY__Project__c,Type__c 
from TASKRAY__Project_Task__c 
where id in :setTaskRayTaskIds
AND Project_Stage__c = null 
AND TASKRAY__Project__c!=null
and type__c in ( 'Idea', 'Feasibility', 'Development', 'Validation and pre-launch','Feasibility','Launch')];

/*Main Tasks to update : main tasks are created from the project , 
Previously at task creation, the selected value in Type field is copied in project_Stage field to identify 
them as Main tasks.(Type values are  'Idea', 'Feasibility', 'Development', 'Validation and pre-launch','Feasibility','Launch')*/
List<TASKRAY__Project_Task__c>lstMainTasks1 = [SELECT TASKRAY__Project__c,Project_Stage__c from TASKRAY__Project_Task__c 
where id in :setTaskRayTaskIds 
AND TASKRAY__Project__c!=null
AND Project_Stage__c in ( 'Idea', 'Feasibility', 'Development', 'Validation and pre-launch','Feasibility','Launch')];

/*We want to update the costs & resources found in the Sub tasks by Type in the Main Stage Task
For Main Task 1, if Project Stage= idea, Each Type= Idea of subTasks of the same project have to be sum up*/
