is there a limit to the number of nests you can have in a nested
IF(ISNUMBER(SEARCH)) functions?

For example, I have one that works properly with 6; for example:

=IF(ISNUMBER(SEARCH("jon",AC2)),"jon",IF(ISNUMBER( SEARCH("bill",AC2)),"bill",IF(ISNUMBER(SEARCH("tom ",AC2)),"tom",IF(ISNUMBER(SEARCH("joe",AC2)),"joe" ,IF(ISNUMBER(SEARCH("rob",AC2)),"rob",IF(ISNUMBER( SEARCH("ted",AC2)),"ted",""))))))


if I add another nest, Excel finds an error with the last search and will
not allow it...

Thanks in advance for your help,

Jonathan
