Switch wiring help

I am trying to change the light switch that controls my ceiling fan/overhead light to a new two-switch - the top switch will control a new outlet, the bottom will control the fan/light.

I pigtailed the two bottom black wires together and attached that wire to the Line In screw. The other black wire I attached to the other screw.

Upon turning on power, the fan/light turned on and stayed on regardless of the switch position. I also tried reversing which wires went to which screws, but that resulted in the fan/light not working at all. What am I doing wrong?

Did you try turning off both switches of the new install?
What did you connect to the third screw for the second switch?
What is the third black wire for? Did it function properly?

Each switch requires 2 wires, a hot source and a switched hot source to the load. The white wire in a 2 wire cable is used for the switched hot source to the load and marked black near the terminations.

On your original switch you had two wires on the same terminal.
When you went to pigtail them you no longer had the same two wires.

There are three existing cables in that box...... one is power in, one is power out and the the third is the fan/light combo. You need to pigtail the power in and power out cable.
