ICar on Upload two values to ThingSpeak with a Arduino GSM Module?

Halo everyone,

I want to upload 2 values to ThingSpeak in feld1 and feld2. I use an Arduino uno and a GSM module for that. I have already work out some code that work but not as good as I want. I am working with the ThingSpeak.h but I don’t think the library good for the use with the GSM Module. The problem with the code below is that die code stops working after the two values are sended to ThingSpeak. So the loop function just stop there. I don’t know why.  Even when after the function writeFields() some more function came. The getLastReadStatus () doesn’t work also. Do you have any idea how to fix this problem? The loop function and the values should send some values over and over again.

Or do you know other methods to upload more very values to ThingSpeak with the GSM module from Arduino?

thank you in advance.
