Hi, can someone help me with this task in Multisim simulation software?

The goal of the project is to implement a counter which is able to count from 0 to 99 and display the result on a 2 digit 7-segments led display. In order to implement the counter you have to use 2 BCD counters and cascade them. Decode the outputs of each counter and connect the displays. The CLK signal is a signal with T= 1s, to obtain the CLK signal you should be able to choose as source from the signal generator, a push button and an oscillator. It is MANDATORY to simulate the project
