Save error. Expression cannot be assigned

Hi, I am trying to create a trigger to start an approval process after insert if a certain field is checked - we are getting this save error: 'Expression cannot be assigned'

 

 

MDFSubmitForApproval on MDF__c (after insert) {

for (MDF__c a : trigger.new) {


if (MDF__c.Submitted__c = 'true') {


Approval.ProcessSubmitRequest app = new Approval.ProcessSubmitRequest();app.setObjectId(a.id);
Approval.ProcessResult result = Approval.process(app);
}
}
}

 

Not sure where we are going wrong with this?  Any help much appreciated.

And

IF (MDF__c.Submitted__c = true)

this should be

IF (a.Submitted__c == true)

if MDF__c.Submitted__c is a boolean value (Check box)

 

try

 

if (MDF__c.Submitted__c) 

or

if (MDF__c.Submitted__c == true)

1) if (MDF__c.Submitted__c = true)

     this should be

     if (MDF__c.Submitted__c == true)

     or

     if(MDF__c.Submitted__c)

2) afterinsert should be after insert
AshanAshan

1) if (MDF__c.Submitted__c = true)

       this will not give a save error. But this is logically wrong.

2) your save error was caused by "afterinsert"
