Using the 'Last' function in a portal
Is there any way to use only the data from the last record in a portal, similar to using the 'Last' function in a repeating field? The data in the portal I am pulling data from can vary from nothing to upwards of 20+ records. It seems like an easy request, but I can't seem to figure out how to do this. By the way, I'm using version FMP 11, if that matters.
