Have a trange problem, I have a series of two macros that work perfectly,
except the first time they are called.

The macros are as follows:

Sub fill_right(r, z)

Dim c
c = 5
Dim temp_range

Do While c < 28
temp_range = Range(Cells(r, c), Cells(z - 1, c))
Call find_abs_max(temp_range, z, c, summarysheet)
c = c + 1
Loop

End Sub


which calls:

Sub find_abs_max(read_range, target_row, target_column, target_sheet)
Dim max_range As Single
Dim min_range As Single
Dim abs_min_range As Single

target_sheet.Activate
max_range = Application.WorksheetFunction.Max(read_range)
min_range = Application.WorksheetFunction.Min(read_range)

If min_range < 0 Then
abs_min_range = -1 * min_range
If max_range abs_min_range Then
Cells(target_row, target_column) = max_range
Else
Cells(target_row, target_column) = min_range
End If
Else
Cells(target_row, target_column) = max_range
End If
End Sub

Basically, I am creating a cutom "find absolute maximum" formula and then
inserting the results in the appropriate cells, i.e. the result row columns 5
to 27. Actually having the formula in the result cells won't work as the
refrenced range (r:z) is deleted and repopulated by preceding macros each
time.

I found that the macros work perfectly fine except for the very time they
are called (i.e. cell row r, column 5), in which the result for the absolute
maximum of 4 cells in r5 to r(z-1) each containing the value 30.48 is zero
(which is obviously wrong). The macros work fine on a separate range with
the exact same values, and on each successive range and reslt row used, so I
am a little stumped as to why they are returning zero for the first run.

Would greatly appreciate any insight to this issue.
