In the link given above just type the value of z score that you have calculated and it will give you its corresponding P-value. If you want to do it using the tables, just check the z table.

Suppose you have calculated a z score of 2.27 and you want to calculate the corresponding P-value.

In the vertical leftmost column search for 2.2 and then from the horizontal look for 0.07 and the value which lies in the column below 0.07 and in the row of 2.2. In this case the value is 0.98440.
