an ambiguous error in this code

[Mohamed Slama]

Hi all

this code :
when i push button (high) that connected to Portb.F0

the counter will increment as follow ( 1 ,3 ,5,7,9, 11, 13, 15 )

and store these values into a vector of length 8

when Portb.f0 pushed down (low) ( the micro controller supposed to display this vector value by value each 400 ms ,But micro controller display these value correctly in the first time but in the second time it display 0 then 0 then ...... to eight zero

third time it display correctly and so on , what is the problem ??
