I have a requirement while inserting and updating of information records ,fetch values from opportunity and populate on Information object . opportunity is a lookup field on Information object.I have tried below code using triggers.  please tell me  where did i mistake.Its very urgent. Thanks in advance.

public static void TMOppCompInfo(List<Competitive_Infomation__c> complst)
    {
        
        List<Infomation__c> lstcompinfo = new List<Infomation__c>();
        set<id> oppid = new set<id>();
        Id TMoppRecord = Schema.SobjectType.Opportunity.getRecordTypeInfosByName().get('machinery').getRecordTypeId();
        Id CloseOut = Schema.SobjectType.Competitive_Infomation__c.getRecordTypeInfosByName().get(' Information - Close Out').getRecordTypeId();
        for(Competitive_Infomation__c comp : complst)
        {
            oppid.add(comp.Sub_Opportunity_Name__c);
         }
       
       List<opportunity> lstoppcomp = [select id,Emissions_Unit__c,Emissions_Guaranteed__c,Reason_for_Guarantee__c,Guaranteed_NOx_15_O2_ppm__c,Liquid_NOx_15_O2_ppm__c,
                                        Guaranteed_CO_15_O2_ppm__c,Liquid_CO_15_O2_ppm__c,CBR_Temperature_Range_Unit__c,Temperature_Range__c,
                                       Load_Range_pct__c,CBR_Engine_Emissions_Controls__c from opportunity where id =: oppid and recordType.Name = 'machinery' ];
      IF(lstoppcomp.size()>0)
     {
        for(Competitive_Infomation__c compinfo : complst)
         {
          
           if(compinfo.Emissions_Same_as_Solar__c == 'same' && compinfo.RecordTypeId == CloseOut)
           {
               for(opportunity opplst : lstoppcomp)
              {
              
                  compinfo.NOx_Emissions_15_O2__c = opplst.Guaranteed_NOx_15_O2_ppm__c;
                  compinfo.CO_Emissions_15_O2__c = opplst.Guaranteed_CO_15_O2_ppm__c;
                  compinfo.Liquid_NOx_Emissions_15_O2__c = opplst.Liquid_NOx_15_O2_ppm__c;
                 
               
           }
         }
       }
