Operands to the || and && operators must be convertible to logical scalar values.

So I don't understand the reason why I am getting the following error:
riskUserId=[];
if (data.A>5) || (data.B==1)
C=data.D;
end
data is a table
A is of type double
B is of type logical (0s and 1s)
I am still getting used to this table logic and cell content type of data.

data.Age>60
? Should there be one age greater than 60 or all ages greater than 60?

riskUserId=[];
%MATLAB is expecting a 1 or 0 for preexisting conditions. IF the values in the table are true/false, use strcmpi(). This would look like (strcmpi(data.Preexisting_Conditions,"true"))
if (data.Age>60) || (data.Preexisting_Conditions==1)
riskUserId= [riskUserId;data.User_ID]; %Stack all values into an array for easy viewing.
end

Use || and && when you are comparing a single (scalar) value. Use | and & when you are comparing arrays (when there is more than 1 output of the comparison).
a = 1:4;
b = 4:-1:1;
% Works
c = a>2 & b<=3
% Error you are seeing
d = a>2 && b<=3
