Help with cylinder solid tool on rhino

Hello, I am new to rhino3d and new to CAD in general. I am stuck and need help with something. Under solid tools, I click cylinder and I want to adjust it, make it bigger, move it around etc. I cannot do this anymore. Everything was fine until an hour ago. I am attaching a picture, now I can only move the shape, I cannot stretch it out and make it bigger like before how do I fix this. I am attaching a picture of a square and it shows the arrows just how I want them.

If someone could help me out, I would really appreciate it. I am still stuck on this. Thank you.

Your picture shows that you have the gumball turned off. It is at the bottom of the screen. Click it back on. That is one way to adjust things, using the square handles of the gumball.—-Mark
