ANSYS fluent Mesh error
 

I'm trying to find the lift coefficient for a UAV model, but I'm stuck on the meshing section. I'm pretty new to ANSYS so I really stuck. I've been following the YouTube video down below step by step but for some reason my model meshing fails. I'm wondering if I could get so information on where I'm going wrong. I've included my model below if anyone wants to see.
