Use one custom indicator output in another custom indicator

[Shashank Kumar]

I have two custom indicators. I wish to use output of one custom indicator in  another custom indicator. However I am unable to do so. I wish to achieve this functionality in code it self.

What changes I need to make in the code below:

1st Custom Indicator:

Please edit your post and use the code button (Alt+S) when pasting code.

EDIT your original post, please do not just post the code correctly in a new post.

1. code button.
   

2. input ENUM_INDICATOR InpMAMethod;
   ⋮
            firstValue+=InpMAMethod[j];

   Do not post code that will not even compile.

I have fixed the mistake apologies for the error. I was trying many things, forgot to paste the one which compiles.

Never mind i found the answer
Switch the order of indicators instead of using output of 1 in 2, I used output of 2 in 1
