I am a .NET Developer and this is my first week developing salesforce applications. I was asked to make a custom salesforce APEX page that performs a "callout" to an external webservice. I was able to do this. However, I am not able to pass in the Account ID from the account page to the new APEX page.

I modiied the account view page to include a command button that redirects to my new APEX page. See code here

<apex:page standardController="Account" tabStyle="Account">
     <apex:pageBlock >
            <apex:form >             
                 <apex:commandButton action="{!URLFOR("/apex/RECALLDEV2",Account.id)}" value="TTM Revenue" /> 
            </apex:form>        
     </apex:pageBlock>
     <apex:detail subject="{!Account.Id}"/>              
</apex:page>

And here is my custom APEX page and Controller that handles the URLFOR redirect

public with sharing class RECALLDEV2Manager 
{
   
    private final List<Account> account;

    public RECALLDEV2Manager (ApexPages.StandardController controller) 
    {
        account = [SELECT Name FROM Account WHERE Id = :ApexPages.currentPage().getParameters().get('id')];
    }

    public string getHelloWorld() 
    {
        RECALLDEV2.WebService2Soap service = new RECALLDEV2.WebService2Soap();
        string responseFromService = service.HelloWorld();
        
        return responseFromService;
    }

}

Here is the Page, I am simply trying to access the account object I populated in the controller and write the company name to the page but it does not appear

<apex:page standardController="Account" extensions="RECALLDEV2Manager">
    <h1>Test Page</h1>
    <apex:pageBlock >

        <apex:form >
            <apex:outputLabel value="{!HelloWorld}" />
            <p>You are viewing the {!account.name} account.</p>

        </apex:form>

    </apex:pageBlock>
</apex:page>
