Error Converting Passed Range into Array in VBA for Excel
 

Your code (not counting the last bits that I don't have) worked ok for me.

Are you sure you're passing the range from the correct worksheet?

For years I've been passing ranges into Excel functions, then converting them
into an array so that I can use them. But today I'm getting an empty array
instead of a full one. If I pass in a 4x4 array my function seems to work.
But when I pass in a 27x10 array I get nada. After the assignment "arrX =
arrayXIn.Value" the debugger shows arrX is the correct size but its empty.
Here's my code. Any suggestions?

Public Function funcExcelGenXXInv(arrayXIn As Range)
Dim arrX As Variant '27 x 10
Dim arrayXPrime As Variant '10 x 27
Dim arrayXpX As Variant '10 x 10
Dim arrayXpXInv As Variant '10 x 10
Dim intNRows, intNCols As Integer

arrX = arrayXIn.Value
'Find size of X array.
intNRows = UBound(arrX, 1)
intNCols = UBound(arrX, 2)

arrayXPrime = funcTranspose(arrX)
arrayXpX = funcMultM(arrayXPrime, arrX)
arrayXpXInv = funcInvMatrix(arrayXpX)
funcExcelGenXXInv = arrayXpXInv
End Function
