Passign params to HTML view

Hi :o)

I have created a HTML view that contains a form and a view.
This is to represent a hosting account and associated email addresses.
The form opens ok with the correct ID number in the address bar - but there is no data in the form and the view is not filtered.

The script behind the view is below:-
----------------------------------------------------
htmlpage Hosting_Detail(Id)
displayname = "Hosting Detail"
content
<%{%>
<div elName='zc-component' formLinkName='Hosting_account' params='zc_Header=true&zc_SuccMsg=Data Added Sucessfully!&zc_SubmitVal=Submit&zc_ResetVal=Reset&ID=<%=Id%>'>Loading ...</div>
<div elName='zc-component' viewLinkName='Email_accounts_View' params='zc_Header=true&zc_Footer=false&zc_SecHeader=false&ID=<%=ID%>'>Loading ...</div> <%}%>

I'm opening the HTML form with the function below which appears to be passing the value ok.
--------------------------------------------------------------------------------------------------------------------------------------
void display.OpenHosting(int Id)
{
    openUrl("#View:Hosting_Detail?Id=" + input.Id + "&zc_Header=false&zc_Footer=false&zc_DelRec=false", "same window");
}

This is in turn called from the code behind the view
--------------------------------------------------------------------------
list Hosting_account_View
{
    displayname = "Hosting account View"
    show all rows from Hosting_account
    (
        Company
        txtPrimaryDomain as "Primary domain"
        txtCPAddress as "Control panel"
        txtBillingAddress as "Billing Address"
        Hosting_Provider as "Hosting Provider"
    )
    custom actions
    (
        "Edit Hosting"
        (
            function = display.OpenHosting(ID)
            show action in view header = false
            show action for each record = true
        )
    )
}

Any help would be appreciated please as pulling my hair out.
have downloaded the CRM app but can't work out how it works.

Many thanks
