Hey guys i've been tryna build this 0-99 counter but i couldn't manage it. Can u help me out with it??

That's too painful to read. Use the code tags to maintain the formatting of your IDE. Put the word CODE inside square brackets at the beginning and a /CODE in square brackets at the end.
 
One thing you appear to be missing is a 7-segment lookup table?
eg. for each digit 0-9, the 8 bit binary or hex value that sets the appropriate segments on?

eg. a char array, so the index is the input digit and the stored data is the segment pattern.

For each digit, get the value in that array using the digit value and output that to the segments, then enable the digit for a few mS.
