Somehow the 7448 ic outputs are not changing even though the inputs are changing. The inputs are from a jk flipflop counter and im having trouble displaying the output of it in a 7 segment display.

It's just stuck to the output 9 or 0. Help.

 

Welcome to AAC!
Show us the schematic of your circuit.

 

What happens if the connect pin-3 of SN7448 to GND?

Here's the schematic in proteus. But i put 1k ohm pull down resistors on the input pins of the AND, OR and JK Flipflop in the breadboard.

Ohh myyy ggodd.. it works!!, I can't believe I didn't try this holyyyy. Thank you soo much

What do you mean it works?
What happens when you connect pin-3 of SN7448 to GND?

My bad, connecting the pin 3 of the 7448 to GND turns on all of the led display of the 7segment.

I got it working by connection pin 5 to GND, it's labeled in the datasheet as RBI

It helps if you read the datasheet.

EDIT: corrected table.

You shouldn't leave any inputs floating.
