Problem with Microsoft Access and prompts

Question

In the past I have used the following prompt to retrieve details for an indivdual location or a total of all the locations from an sql database:
@Select(Claim DetailLocation) IN @Prompt('Select Location(s) or type ALL:','a','Claim DetailLocation',multi,free) OR  'ALL' IN @Prompt('Select Location(s) or type ALL:','a','Claim DetailLocation',multi,free)
E.G
When 'All' is selected the data retrieved would be total sales for All locations = £100
When I attempt to use the same prompt on an Access database it works when I select an indivdual location, but when I select 'All' it retrieves the data for the individual locations
E.G. 
When 'All' is selected the data retrieved would be total sales for location 1 = £20                                                                               
total sales for location 2 = £80
Does anyone know how I can retrieve the data from Access using 'All' and obtain one total figue (as per SQL) and not  as a series of location amounts?
Regards

Answer 1

Just a question of clarification:
Are all the columns of ttype String?
Make sure only value of String type should be in single quotes.
Other primitives such as int, double, short, etc should not be in
single quote.
Are MemberID, Age String type? If not take out the single quote around
their respective value.
Its in order. but it still cant work correctly.
heres my code:
String addNewMember = "INSERT INTO Member(MemberID,
First_Name, Last_Name, Nric,Gender, Age, BirthDate,
Address, PostalCode, Res_Phone, Email, DateOfRegister,
DateOfExpiry)";
addNewMember += "values('"+memberID+"',
D+"', '"+firstname+"', '"+lastname+"', '"+nric+"',
'"+gender+"', '"+age+"', '"+birthdate+"',
'"+address+"', '"+postalcode+"',";
addNewMember += "'"+resphone+"', '"+email+"',
l+"', '"+registerDate+"', '"+expiryDate+"');";
stmt.executeUpdate(addNewMember);
