You put the sort option in the portal options?
I tried and Its not really a sort but show only certain records based on a non portal selection...
I am editing the File Maker productivity kit that is based on sales order to change to Purchase Orders that is free from filemaker.
I can send the file?
Well then what you are looking for is called a Filtered Portal. You should set a global field with the data you selected and then the portal relationship will be keyed from that global to the field in teh child table. There are numerous examples of this on the net. Just do a search for filtered portal and filemaker.
