So I just learned that I can create a user form and build it to the desired setup, but I don't know how to assign functions or macros to make it work. Here is what I have now.
Delete Rows.jpg

Could someone help direct me to be able to set it up to do something along the lines of this macro:
Sub Delete_Rows_User_Input()Dim rng As Range
Dim InputRng As Range
Dim DeleteRng As Range
Dim DeleteStr As String
xTitleId = "Delete Rows"
Set InputRng = Application.Selection
Set InputRng = Application.Intersect(Range("$A$1:$O$1000"), Range("$A$1:$J$1000"))
'But rather than just have one input, I'd like to be able to select multiple inputs, where if the table has either "A" or "B" in any cell within the table. (Hence why I'm making the user form)
DeleteStr = Application.InputBox("Select Valuse to Delete", xTitleId, Type:=2)
For Each rng In InputRng
    If rng.Value = DeleteStr Then
        If DeleteRng Is Nothing Then
            Set DeleteRng = rng
        Else
            Set DeleteRng = Application.Union(DeleteRng, rng)
        End If
    End If
Next
'a problem when running this macro, is it gives an error code when I click cancel on the normal inputbox, so could the user form be designed to go through an error handler and move to a 'save' part of the macro rather than just exit sub?
DeleteRng.EntireRow.Delete
End Sub
Thank you for any assistance!!!

Cheers!
