I purchased this Laptop desk HIS818-Z and having major problems assembling it. I can’t even get the screw into the hole to attach the rail. 

The box’s instructions “Step 1” is completely different from the Wayfair site’s “Step 1” directions.  

Wayfair indicates to detach the rails provided.  These rails do not detach. 

Please advise some type of help prior to me returning this item.
