I have been trying to find some information, without success, about this:
I have 3 variables that might, or not, have a value on it. I would like to check all 3 and if any one has the value I want to create another variable with its own value.
something like this:
if (var1 OR var2 OR var3 == 'yes'){var4='anothervalue';};
I have no idea what is the symbol for the condition 'OR'.
