Per the documentation for this package, I have created a data source and a named map in the MapBuilder section. Next, I have called @Html.RenderMap(MAPALIAS) with the name of my map in my view.

When attempting to load a test page with this view I receive this error:

System.Web.Mvc.HtmlHelper

• Is there a specific @using declaration I need to add for this package to work correctly?
• I am running version Umbraco 7.5.3, does this package not support this version?

Thank you

My code for reference:

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage
@{
    Layout = "MasterLayout.cshtml";
}
<div class="body-container">
    <div class="center-content float-center">

        <div class="contentBox">
            <div class="goldstripe"></div>
            <span style="font-size: 12px">@Umbraco.RenderMacro("Breadcrumbs")</span>
            <h1 class="largeHeader show-for-large">@Umbraco.Field("pageName")</h1>
            <br/>
            @Html.RenderMap(allLocations)
        </div>
    </div>
</div>
