Hello--I am new to FileMaker (from Excel) and am trying to set up a function (I believe) that will tell me someone if a member. For example: I have a membrship database where under "Member Type" I have set up 5 radio buttons with our different types of membership. On a differnet layout I want to track those members (and others) who attend our annual conference. On the 2nd layout I want to put a field that will look at the "Membership Type" field and return a "yes" if one of the radio butoons is clicked or a "no" if none of them are clicked. What is the best way to do this?

Much thanks, in advance!

Calculation field equals: If (IsEmpty (Member_type, "", "yes")

You are checking whether a single set of conditions exists, so use 'If'. (For multiple situations, use the 'Case' function.) IsEmpty returns true if the field contains no value, and the calc will return a null string; otherwise it returns "yes". Remember to choose "text" as the result type of the calc.

Thanks for the reply. I have tried what you mentioned but it keeps telling me that the "field cannot be found." I picked that field off the list so not sure what to do know. Here is what I put in--2001 Membership Type is the filed. When it says it cannot find the field it only highlights Membership Type and the hyphen before it. Do I have something set up wrong with that field?

If (IsEmpty (2001_Membership_Type, "no", "yes")

Any suggestions?

Look in the list of functions in the calculation dialog: I'll bet the delimiter character is semicolon, not comma.

Type the calculation again only use a semicolon.

If you actually typed in FM what you have in your thread, it should red:

IF(IsEmpty(_Membership),"Yes","No")

Thanks everybody for all your help. I figured it out. My problem was the field name. It would not recognize starting the field with "2001." Once I changed the field name it worked perfectly. Here is what my calc field reads now.

If(IsEmpty(Membership Type 2001), "no", "yes")

Thanks again--one headache gone!!

Ahhh yes. FMP even gives a warning that field names starting with digits or containing certain characters won't work in calculations, but it's amazing how often it goes unheeded.
