I can't figure out why my Statements:
If Worksheets(Usersheet).Name < wsSheet.Name Then
and
If Worksheets(Usersheet).Name = wsSheet.Name Then
don't work.

This code is supposed to highlight the dependents on all
sheets of the selected cell, but it doesn't compare
correctly and it highlights all the cells without regard to
the Sheet the the cell came from. If you can help and
provide explainations of what I did wrong and how I can
improve it, I would be very thankful.

Dim wsSheet As Worksheet

If txtFormBox.Text < "" Then
'FINDS BOTTOM RIGHT CELLS
If WorksheetFunction.CountA(Cells) 0 Then
'Search for any entry, by searching backwards
by Rows.
LastRow = Cells.Find(What:="*", After:=[A1],
SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row
'Search for any entry, by searching backwards
by Columns.
LastCol = Cells.Find(What:="*", After:=[A1],
SearchOrder:=xlByColumns, SearchDirection:=xlPrevious).Column
End If

For i = FirstCol To LastCol
For j = FirstRow To LastRow
On Error Resume Next

txtFormBox.Text) 0 Then
