Coversion problems

The following line of code :

If objdataset.Tables("Owners").Rows(i - 1).Item("itemClientID") =
Me.lblID.Text Then
'
'
end if

Produces this error :

"Cast from string "" to type 'Double' is not valid."

Can someone help out?

Thanks in Advance

CType(Me.lblID.Text, Double) Then

'
end if
