i am trying to run this piece of code.  it works fine if the array is only 1 column wide but now i need it to have 2 columns it runs 1 loop ok then stops with the error "subscript out of range"

For i = 1 To UBound(arrParagraph)
ReDim Preserve arrParagraphData(i, 2)
arrParagraphData(i, 1) = arrParagraph(i)
arrParagraphData(i, 2) = 5
cmbParagraph.AddItem arrParagraph(i)
Next

Hi,
Perhaps you should move the ReDim out of the loop.

Dim x as Integer

x = UBound(arrParagraph)
Redim Preserve arrParagraphData(x, 2)

For i = 1 To x
   arrParagraphData(i, 1) = arrParagraph(i)
   arrParagraphData(i, 2) = 5
   cmbParagraph.AddItem arrParagraph(i)
Next

You cannot do that.  You will have to change it to something like:
ReDim Preserve arrParagraphData(2, i)

EDDYKT,

>>You can do that if you define<<
From BOL:
<quote>
If you use the Preserve keyword, you can resize only the last array dimension, and you can't change the number of dimensions at all. For example, if your array has only one dimension, you can resize that dimension because it is the last and only dimension. However, if your array has two or more dimensions, you can change the size of only the last dimension and still preserve the contents of the array.

acperkins,

you are right if you've already defined that as 2 dimension array.

However, I just declare as variant
