Multidimensional arrays

I am trying to create a multidimensional array and am recieving a
I am trying to create a multidimensional array and am recieving an error
Object reference not set to an instance of an object. Is my array setup correctly? If I don't use an array I don't recieve errors and all my data prints out on response.writes.

Dim i as integer = -1
Dim row As DataRow
Dim k As Integer = 0
Dim thelist as string
Dim thepropID as String
Dim oldstate as string = " "
Dim proparray( , ) as string
Dim strVDS as string
Dim arraybounds as integer
Dim rowscount as integer = empDS.Tables("properties&quot.Rows.count

For Each row In empDS.Tables("properties&quot.Rows
If empDS.Tables(&quot;properties&quot.Rows(k).Item(&quot;propName&quot <> oldstate Then
i = i + 1
oldstate = empDS.Tables(&quot;properties&quot.Rows(k).Item(&quot;state&quot
End if
proparray(i,0) = empDS.Tables(&quot;properties&quot.Rows(k).Item(&quot;state&quot
proparray(i,1) = empDS.Tables(&quot;properties&quot.Rows(k).Item(&quot;propName&quot + &quot;|&quot; + empDS.Tables(&quot;properties&quot.Rows(k).Item(&quot;propName&quot
proparray(i,2) = empDS.Tables(&quot;properties&quot.Rows(k).Item(&quot;xscale&quot + &quot;|&quot; + empDS.Tables(&quot;properties&quot.Rows(k).Item(&quot;xscale&quot
proparray(i,3) = empDS.Tables(&quot;properties&quot.Rows(k).Item(&quot;yscale&quot + &quot;|&quot; + empDS.Tables(&quot;properties&quot.Rows(k).Item(&quot;yscale&quot
proparray(i,4) = empDS.Tables(&quot;properties&quot.Rows(k).Item(&quot;propID&quot + &quot;|&quot; + empDS.Tables(&quot;properties&quot.Rows(k).Item(&quot;propID&quot
k = k + 1

You must declare the bounds of your array. For example, instead of having:

Dim proparray(,) as string

You could have:

Dim proparray(5, 100) as string

Or:

Dim Dimension1Size as integer = 5
Dim Dimension2Size as integer = 100
Dim proparray(,) as string
Redim proparray(Dimension1Size, Dimension2Size)

thanks. I didn't realize I need to do this.
