SSRS Report Issue - The Visibility.Hidden expression for the tablix has an incorrect number of parameters for the function RowNumber
<p>We have a single page SSRS report that I am attempting to turn into a multi-page report that returns several records. Currently there is no tablix / matrix grouping in the report, which I am understanding is needed in order to be able to utilize the 'next' function to return more records. </p>

<p>I very simply added a list to my report and copied and pasted the fields into the list so that there is a grouping. However, I am now receiving and error - "The Visibility.Hidden expression for the tablix has an incorrect number of parameters for the function RowNumber".</p>

<p>I do a fair bit of <strong>simple</strong> SSRS reports, but this one is beyond me and I'm not entirely sure where to start diagnosing or what information I need to provide. </p>

<p>Thank you, please let me know if I need to provide additional information. </p>
