<div>There are a several problems:<br>
<br>
1) Every time through the loop, you are overwriting your existing
Year_52, so only the last iteration will control the end result.<br>
2) Week_same(i) contains the index where the two weeks are the
same, but then the equality in the where statement is checking for
equality of that *index* with the *values* of year_52. Unless the
values of year_52 are equal to the index, this is probably not
what you want.<br>
3) This code will fail if more than one value in week_52 and
week_53 match.<br>
<br>
I'm not sure exactly what you are trying to do, but I believe this
structure is either wrong or just more complicated than you need.
Can you tell us what you are trying to accomplish (i.e., what you
expect Week_52 and Week_53 to be at the end)?<br>
