We don’t know… can you? 
First, please edit your post and format the code so that it will show properly, as per: Welcome to Blynk
Then, a better question would be like… “I have taken this code and tried this, that or the other, but had XYZ result, any suggestions?” (and show examples). Basically, read the docs, study other arduino learning sites and try to do it yourself first, don’t just ask how.
