        }
    }
    

    }

So theres some of the prelimary, now i have coverage on everything there minus a apexpages.addmessage, but thats just one line so i don't mind right now. my main issue is this
 

//Test, please don't delete
    /*public void myTest() {
outputComment = inputComment; 
}*/
    
    public PageReference removeRecord() { 
        outputSer = inputSer; 
        Risk_Analysis__c removedItem; 
        if(MapCheckSer.containsKey(inputSer)) {
            removedItem = MapCheckSer.remove(inputSer); 
            serListAllNew.clear();
            serListAllNew = MapCheckSer.values(); 
            PageReference page = new PageReference(ApexPages.currentPage().getURL()); 
            page.setRedirect(true); 
            return null; 
        }
        else if(MapCheckExist.containsKey(inputSer)) {
            removedItem = MapCheckExist.remove(inputSer); 
            serListHistory.clear();
            serListHistory = MapCheckExist.values(); 
            PageReference page = new PageReference(ApexPages.currentPage().getURL()); 
            page.setRedirect(true); 
            return null;
            
        }
        return null;

The else if statement, i can't get that to get coverage. Now i was handed this code and told "hey intern finish test coverage, get it to 90%" i'm at 87%.... :( 

now if i don't have data for either the if line will be covers and the else if line will be covered but obviously it wont cover 
 

else if(MapCheckExist.containsKey(inputSer)) {
            removedItem = MapCheckExist.remove(inputSer); 
            serListHistory.clear();
            serListHistory = MapCheckExist.values(); 
            PageReference page = new PageReference(ApexPages.currentPage().getURL()); 
            page.setRedirect(true); 
            return null;

I'm stuck..
