DIY Counter Circuit Answered

Currently I am creating a counter circuit. Ideally, I would like it to use a 555 timer, two 7-segment displays (so it could count from 0-99), 4026, picaxe 08M2 (so i could program it to switch off after a period of time without resting the 7-segment display), an LED (to indicate that the circuit is still on) and a piezo buzzer that would read the amount on the 7-segment display.

Also, i'd like it to have three switches: one that resets the 7-segment display, one that adds a number to the count and one that reads the count/ amount of the 7-segment display.

I have attempted to create this circuit but they are not successful (seen below). BTW it is not complete because i was trying to develop it.

At this point I am stuck on what to do now, any help or point in the right direction would be greatly appreciated. Thanks.
