Water sim not rendering

Ok so Im new to sims this is my first time using them so i was following this one guys tutorial and it involved a water sim poring into a glass so when i finished i wanted to render it so i render and when it was finish the water was gone but in the render preview i can still see the water any ideas would be helpful

this is it after the render


i would show you it in the preview but im fairly sure you cant

Rather than showing us the render you should be showing us your scene and render settings as well as a link to your blend file.
We are having to guess what ALL of your hundreds of settings are based purely on that single image !!
It’s like asking your doctor to diagnose an illness just by giving them a photograph of your toe nail

Check your materials are correct
Check your render layers are correct
Check your modifier settings are set to display at render time
Check your outliner for objects that you have set to be non renderable

Sorry about that Im am new to this forum i was going to but it wont let me up load it for some reason i would send you a fbx but that would change all of my settings
