Hi, i would like to know how to use logical operators in templates with #if: statements. For example, i want to check if there are values at the same time in two parameters, and the template has to do one thing if there are these two values, and another thing if there is only one value in either the first or the second parameter, like this:

but I saw that "&&" does not work. What I have to do?

Thanks in advance.
