Your brackets are the cause of the problem . The correct form of your code should be like this:
Generally if you want to check more than one condition :
1- the number of brackets before the first condition should be equal to the number of your conditions
2- you should have 2 brackets after every condition except the first one (only one bracket)
Notice: The brackets control how you want the If command to be read above is the solution for your case only (which is the most common error even if you are checking more conditions than I am used to . I usually don’t check more than 3. 
).
And you can find here everything about how to use if statements and conditions on the Wiki
I hope I could help I had the same problem long ago and it was annoying
