Hello Everyone!
I hope you all are doing well, I am stuck on a problem in my code ( attached below ). I am using a thingspeak server to receive data, All other aspects are working fine, but I can't seem to make the GPS module work ( I am using ublox Neo 6m ). I receive 0.00 for both longitude and latitude values on the thingspeak Server, but the Gps Module seems to work fine as I see the Led Indicator. In my opinion, there is a problem with the if-else statement, but I Can't Figure it out. Please Help me to get it to work!

, and I think I may have encountered another problem. I have attached the code and Serial Monitor below.
