How to extract a number using Get OCR activity

I want to extract a number and I am storing that number into a string and I am able to extract an integer properly but whenever there is 0 it shows me error stating
" Assign Value For Selecting Number From Text Of All References In EndNote: Specified argument was out of the range of valid values. (Parameter ‘i’) ". I have pasted a photo in which the blue marked area will have an integer and even it may have 0 so how can I get 0 number extracted using Get OCR activity

Thanks
