Hi Jyo1105,
Thanks for your question. Based on my research and experiences, the issue may be caused by you set the @CenterID
is a multiple values parameter.
If in this condition, you couldn’t use the expression of
Parameters!CenterID.Value directly, you
should use a join() function on the parameter to merge the whole values, or add a sequence number behind the expression to use a specific value, just like this:
=join(Parameters! CenterID.Value) or
=Parameters! CenterID.Value(0)
If your issue still exsits, please feel free to let me know.
Thanks,
