Not sure I understand, Ken. Your first statement puts searchString
in the fifth column, while the second puts it in the fourth. If I
changed mine to
filter theData with "*" & tab & searchString & tab & "*"
filter theData with "*" & tab & searchString & "*"
it would still find the string in the second column, but perhaps in
higher columns too because the pattern can be shifted right.
