Reference Empty Data Set

I have a dataset that sometimes is empty. I have it as a detail row in a table on the report, but since the dataset is null the row does not appear. What I would like to do is have it say "No results" if there are no results, otherwise have it show the results.

I tried to add a textbox and reference the textbox on the table, but it was a no go.

Here is what I had in my textbox

<code>
=code.noRows(ReportItems!table8!textbox30)
</code>

and this is what I was using in the code

<code>
Function noRows(byVal result) as string
if result = "" then
noRows = "NO Results"
else
noRows = result
end if
end function
</code>

Can anyone assist me with how to do this?

Thanks
