Hi Rob

What did you mean here?

I want to query all properties that have more than a selected amount of bedrooms.

All properties of current document? All documents?

In the code example you are trying to get child nodes:

selectionNodes = CurrentPage.Children() .Where("documentTypeAlias == \"vehicleDetailPage\"") .Where("selectorBerth >= @0", berthV) .Where("Visible").OrderBy("createDate desc");

I would rewrite your code like that:

int berthV = 3;
var selectionNodes = Umbraco.AssignedContentItem.Children()
    .Where(x => x.DocumentTypeAlias.Equals("vehicleDetailPage"))
    .Where(x => x.HasValue("selectorBerth") && int.Parse(Umbraco.GetPreValueAsString(x.GetPropertyValue<int>("selectorBerth"))) >= berthV)
    .Where(x => x.IsVisible()).OrderByDescending(x => x.CreateDate);

The most interesting code is:

int.Parse(Umbraco.GetPreValueAsString(x.GetPropertyValue<int>("selectorBerth"))) >= berthV

x.GetPropertyValue - returns id of value in radio button

Umbraco.GetPreValueAsString - returns value of prevalue in string

Hope it makes sense for you.

Thanks,

Alex
