Portal Filtering Based Upon a Text ID
I am very, very new to FileMaker and I'm trying to make a member database for a local pool/tennis club. I've been able to set it up and figure out the workings of FileMaker for the most part, including a member check-in function in which a seperate database stamps a member's first name and last name, as well as the time and date that they enter the club, all at the click of a button. The issue I'm having is that I want to use a portal function to display the dates and times of entry for specific members using a portal function to that external database. I've tried to set up the filtering numerous times and using a number of different calcuations, but altogether, FileMaker seems incapable of filtering this master record based upon first and last name. Any suggestions as to where I am going wrong are greatly appreciated.
