Hi Ben,

You advise was perfect select case works like a charm! I ended up
using two slides this is the general gist of the script.

		Select Case Shapes.RESP
			Case strHit1 = c.GetAttrib("a") And strHit2 = c.GetAttrib("b")
				Shapes.ACC = 1
			Case strHit1 = c.GetAttrib("b") And strHit2 = c.GetAttrib("a")
				Shapes.ACC = 1
			Case strHit1 = c.GetAttrib("c") And strHit2 = c.GetAttrib("d")
				Shapes.ACC = 1
			Case strHit1 = c.GetAttrib("d") And strHit2 = c.GetAttrib("c")
				Shapes.ACC = 1
			Case Else
				Shapes.ACC = 0
		End Select

	End If

For the second slide

	Select Case Shapes1.RESP
			Case strHit3 = c.GetAttrib("a") And strHit4 = c.GetAttrib("b")
				Shapes1.ACC = 1
			Case strHit3 = c.GetAttrib("b") And strHit4 = c.GetAttrib("a")
				Shapes1.ACC = 1
			Case strHit3 = c.GetAttrib("c") And strHit4 = c.GetAttrib("d")
				Shapes1.ACC = 1
			Case strHit3 = c.GetAttrib("d") And strHit4 = c.GetAttrib("c")
				Shapes.ACC = 1
			Case strHit1 = c.GetAttrib("a") And strHit2 = c.GetAttrib("b")
				Shapes1.ACC = 0
			Case strHit1 = c.GetAttrib("b") And strHit2 = c.GetAttrib("a")
				Shapes1.ACC = 0
			Case strHit1 = c.GetAttrib("c") And strHit2 = c.GetAttrib("d")
				Shapes1.ACC = 0
			Case strHit1 = c.GetAttrib("d") And strHit2 = c.GetAttrib("c")
				Shapes1.ACC = 0
			Case Else
				Shapes1.ACC = 0
		End Select

	End If

Thank you for all of your help it has been most enlightening!

Becky
