Hi, my worksheet contains six columns, column A has a description, and
column B - F has a validation wherein users enter an "X". My problem
is:
1. Does anyone know of a script that highlights the entire row with a
certain color if an X is entered on Column B - F (different colors for
each column, and I have the color codes already).
2. Prevents users from entering two "X"s on the same row
3. Allows users to delete an "X" from a column, and clears the row of
any colors.
Hopefully someone can help me, because I've searched high and low for
this, to no avail. Thanks!

Your best bet would be a macro, triggered either manually or via a
change event.
I'm sure there are much more efficient ways, but a start would be
along the lines of:
(note: untested)

Sub colortest()
For x = 2 To Range("A65536").End(xlUp).Row
numberofx = 0 'simple counter to confirm each row only has one X
For y = 2 To 6
If UCase(Cells(x, y).Value) = "X" Then
numberofx = numberofx + 1
Select Case y
Case 1: Cells(x, y).EntireRow.Interior.ColorIndex = 6
Case 2: Cells(x, y).EntireRow.Interior.ColorIndex = 7
'etc for each color
End Select
End If
Next
If numberofx = 0 Or numberofx 1 Then Cells(x,
2).EntireRow.Interior.ColorIndex = xlNone
Next
End Sub
