How can I create a custom calculation which will determine if any blanks in a sequence have peaks?

I am having this issue elsewhere as well. How can I report in the results table that nothing was detected? Example below of another custom report section where no peaks which fit the criteria are reported. How can I report that this blank space is due to lack of peaks which fit my criteria? 

UPDATE:

I solved my original challenge by creating a custom calculation that counts the number of peaks at the injection level and using that count in my blank evaluation criteria. However, my second issue persists. How can I report that a table which has all peaks filtered out of it is intentionally left blank because no peaks fit the criteria?

Hello,

It may depend on where you have the filter, but if the table is empty due to a filter on a table you can use the advanced setting below.

I just tried that and it still did not report anything in the table. Could another setting I have be in conflict with it?

Hello,

I would guess there is a filter on the outside group that keeps the entire group from displaying not just the table. In order to work, the table has to be empty not the group.

Thank you yet again, looks like I had one filter I had forgotten to remove which made the entire group empty. Our reports are looking good now.
