if nested

Question

Hi. I have a doubt in nested if's 
 here, if the first condition is true, then it will be return the statement "should be 18 digits". If it's false, I want null value to be returned. Since I am using nested if's its returning "must be numerical and no more than 12no's". how can we resolve this. Can someone help me here?

 To be clear, the second if() will only ever execute when the first if() resolves to FALSE . 
 If this is not what you want to happen , then you will need to restructure your if() nesting to flow logically per what you want to happen.

 This is not possible. As I explained earlier , the second if() only ever executes when the top-level if() evaluates to FALSE. 
 I suggest you review and get more familiar with the precedence in which nested if() statements execute. Namely, that they execute stricly in order from the top-most level, and any nested expressions will only ever be evaluated when the parent condition evaluates in such a way as to call that particular child path (i.e. either the "true" path or the "false" path).
