Having trouble with the coding

Research a lots of coding and the way it works on the community such as

but still got the same results with no output on the blynk. if i erase all the delay for the LED, then how should i make the LED blinking. and I use 2 Gauge on the Blnyk Apps for Metal (V10) and Non Metal (V12) both is PUSH. My connection is USB type
