I take it that you are filtering the values listed in a value list?
If this is not the case, please use Post a New Answer to explain what you want in more detail.
If so, this is a conditional value list. See: "Adventures in FileMaking #1" for 8 different ways to set up a conditional value list.
What i've done, is in my tblChef there is a primary key, which is generated on commitment, Name which is a text value, Date of birth (named DOB) which is a date field, Age which is calculated from the Age field, and Then their Skill Field (Named Skill). What i want is in my table Booking (tblBooking) i'm trying to get a drop down menu with only the options of the Theme selected for the booking.
Ive Attached some screen shots for you, and again thanks for the help
ps. dont think of it doing my homework, think of it as helping me to not fail
Then as I suggested in my last posted comment here, you want a conditional value list. Please see the recommended file for a detailed description of how to set up a conditional value list. The examples include assigning records into multiple categories such as assigning each chef to multiple Themes
