Using figma

I’m trying to put lines on some squares on my frames but it’s going behind the squares instead of in front of them. Can someone tell me how to change the settings. I’m still fairly new

Can share print screen?

yes, I can.

If you right click on a layer, you have bring to front and send to back actions. You can also just order the layers in the layer tree.
