This is driving me insane, all I want to do is check whether the information contained in a cell is present in an array of cells or not, it's substring and I'm checking against an array of strings, but it just wont fu#$%@ work.... I'm using this =IF(NOT(ISERROR(FIND(A1;$C$1:$C$388;1)));"true";"f alse") that's all, if it finds the substring it should return true else false, the thing is that the substring is actually a numeric sequence, here's an example of the worksheet:


----A------------------B----------------------C
1 1234-------------FUNCTION-----------5678_hh_buzzzz
2 5678-------------FUNCTION-----------9866_hh_buzzzz
3 9866-------------FUNCTION-----------1237_hh_buzzzz
4 5248-------------FUNCTION-----------9975_hh_buzzzz
5 1237-------------FUNCTION-----------0832_hh_buzzzz



so I'm checking if values from column A are present in any of the values of column C, using the aforementioned function on column B, it will return false for all, even for the ones I KNOW are there, the funny things is that if I change the search text to "hh" or "buzzzz" it will return true, it seems to be having problems with the numbers somehow.

Anyone knows what might be the problem?
