title: Excel logical statement
body: <p>I want to accomplish a certain task in excel. 
  I want to practice 10 key skills. </p>
  
  <p>I have typed numbers in column A(cells, A1,A2,A3,etc.).  I want to retype them in column B.  Then (if column B matches column A) would like to have the word "OK" appear in column c.  Can write the simple IF statement for A1=B1. Do not know how to make the statement automatically apply to other cells(i.e if A2=B2, A3 =B3, etc). </p>
  
  <p>Thanks. CD</p>
