VS 2012 object reference not set error (array.FindAll

$
0
0
I get error #91 at line 114 (Object reference not set to an instance of an object).
What do I need to do to correct that.
(I get the error either pre-declaring X or as it is now)

Thanks


Code:

Dim iterAAA As Single = 1
54:
55:    Dim arraydciP(3) As String
        Dim quantosDCIa1nosP As Single
59:    Dim quantosDCIa2nosP As Single
60:    Dim quantosDCIa3nosP As Single
61:    Dim quantosDCIa4nosP As Single
62:       
72:    Dim arrayoa(3) As Object
73:    arrayoa(0) = oa1
74:    arrayoa(1) = oa2
75:    arrayoa(2) = oa3
76:    arrayoa(3) = oa4
77:    Dim arrayop(3) As Object
78:    arrayop(0) = op1
79:    arrayop(1) = op2
80:    arrayop(2) = op3
81:    arrayop(3) = op4
82:    Dim quantosdciAnosP(3) As String
83:    quantosdciAnosP(0) = quantosDCIa1nosP
84:    quantosdciAnosP(1) = quantosDCIa2nosP
85:    quantosdciAnosP(2) = quantosDCIa3nosP
86:    quantosdciAnosP(3) = quantosDCIa4nosP
87:

104:    For n As Integer = 1 To P
105:        arraydciP(n - 1) = arrayop(n - 1).dci
106:    Next
107:   
111:
112:
113:    Do While iterAAA <= A
114:        Dim X() As String = Array.FindAll(arraydciP, arrayoa(iterAAA - 1).dci)
