Need Help with Custom Controller & VF Page Please

Can anyone provide insight into what I need to do to prevent my page from displaying Territories that return zero results?

They are currently showing because I made a list and my VF page loops through all “Close Date (Forecasted)” fields  in the list using apex:repeat. Then an inner apex:repeat loops through all territories in the territory list.

The problem is that there are not always opportunities that are in both lists. This causes

public class ForecastController {
    
    public List<Opportunity> opportunities {get;set;}
    public String[] closeDates {get;set;}
    public String[] terrs {get;set;}
    
    
    public void load(){

Hi Greg, I hope you are well. For the line that states <apex:pageBlock title="Territory {!t}" >, I think we'll have to use the rendered attribute and  associate it with a formula expression. If it returns true, then it'll show on the page if it returns false then it won't.

I was thinking of something like <apex:pageBlock title="Territory {!t}"  rendered="{!If(NOT(ISNULL(CONDITIONAL_CRITERIA)),'true','false')}">

The rendering attribute should control which territory pageblock is shown.

The part I am unsure about is what the conditional criteria should be.

Hey Christan, I appreciate the reply. Yeah I am not sure what the solution is either.
