Excel! How can I use a variable in an autofilter in VBA?

[alskdjfhgzmxncbv]

I want to use a variable as the criteria for an autofilter.
What I have is this:
ActiveSheet.Range("$A$1:$S$277").AutoFilter Field:=1,
Criteria1:=">=StartDate", Operator:=xlAnd, Criteria2:="<=EndDate"
where StartDate and EndDate would be assigned date values to filter between
those dates. Results are no records as the variable name is used instead of
the value of the variable.
Variables are dim'ed as variants.
Thanks.

Try
Criteria1:=">=" & StartDate

Search for "Range.AutoFilter" and you'll see this note:

Range.AutoFilter

The AutoFilter method of a Range object is a very curious beast. We are forced
to pass it strings for its filter criteria and hence must be aware of its string
handling behaviour. The criteria string consists of an operator (=, >, <, >=
etc.) followed by a value.

If no operator is specified, the "=" operator is assumed. The key issue is that
when using the "=" operator, AutoFilter performs a textual match, while using
any other operator results in a match by value. This gives us problems when
trying to locate exact matches for dates and numbers.

If we use "=", Excel matches on the text that is displayed in the cell, i.e. the
formatted number. As the text displayed in a cell will change with different
regional settings and Windows language version, it is impossible for us to
create a criteria string that will locate an exact match in all locales.

There is a workaround for this problem. When using any of the other filter
criteria, Excel plays by the rules and interprets the criteria string according
to US formats. Hence, a search criterion of ">=02/01/2001" will find all dates
on or after 1st Feb, 2001, in all locales.

We can use this to match an exact date by using two AutoFilter criteria. The
following code will give an exact match on 1st Feb, 2001 and will work in any
locale:

Range("A1200").AutoFilter 2, ">=02/01/2001", xlAnd, "<=02/01/2001"

============
So in your case:

ActiveSheet.Range("$A$1:$S$277").AutoFilter Field:=1, _
Criteria1:=">=" & format(StartDate,"mm/dd/yyyy"), _
Operator:=xlAnd, Criteria2:="<=" & format(EndDate,"mm/dd/yyyy")

That is 100% absolutly correct for what I wanted to do. Now my report works
exactly as I wanted.
Thanks.
