Hi pottebaumspencer,
In Reporting Services, we can only use Visual Basic functions to manipulate the data that is displayed in text boxes or that is used for parameters, properties, or other areas of the report. But we are not able to use function to achieve interaction feature
with users. Currently, it’s not supported to use Inputbox() function in report builder 3.0.
If you have any question, please feel free to ask.
Best regards,
