How can I use multiple if statements in a calculation

I have a membership form and the price they pay is determined by the length of time they want their membership AND their chosen payment method.

In a calculated field i need to be able to say IF membership length is equal to 1 year AND payment method is Direct Debit then price equals x.

As far as I can see I can't do more than one IF statement.

Yes you can combine two conditions but they will have the same result. To do that please check the video below, there is a "+" blue sign. You need to click on that and add another IF, conditional logic.

Please let us know if you have any other question.
