Cannot Open File - iCustom Error

New comment
 

I am trying to return a value from an indicator buffer via iCustom, but I keep getting the error 'cannot open file':

'2018.09.17 11:09:53.368 cannot open file 'C:\Users\ryanw\AppData\Roaming\MetaQuotes\Terminal\1DAFD9A7C67DC84FE37EAA1FC1E5CF75\MQL4\indicators\ADX & ADXR.ex4' [2]'

I have declared the external variables in the correct order and everything appears to be written in the correct way:

Value=iCustom(NULL,1440,"ADX & ADXR",C,B,0,1);

But the error still appears.

I have posted the full code from the custom indicator and from the EA below.

You should really rename it to something without spaces and non alphabetic characters.
