You all not understanding I was able to switch between to either hide or reveal then I was only able to reveal my brush size is the same and my flow is the same but it not working when switch to white.
It could be your not understanding what we write either. Many here are experts on using Photoshop and masking. It clear Masking is not working for you the way you want the way you state it use to work. Therefore something has changed in your setup. You stated that black use to reveal and and white hide. In reality black does both hides and reveal. It hides areas in the layer the layer mask is on which reveals what is in lower visible layers. You state white reveals again it does both it reveals and it hides. If the current layer mask was hiding area in the layer its on which reveals what is in lower visible layers when you paint with white it will hide what is in lower layer by revealing what is in the layer it on. Layer masks are like a stencil Black cuts out what is in the layer white leave what is in the layer there. Also visible layers above a masked layer can hide all layer below and any effect a lower layer mask may cause.
As Noel wrote some screen grabs showing your image window, layers palette showing layers and target layer mask, tool pallet and tools option bar for your brush tool active and the areas your painting Black and White and will enable some here to help point the way and shade light on your problem.
