help with multiple DS18B20 sensors activate one relay on max temp

can some one help me with this i am trying to get readings from all the sensors and activate a realy if any of them go outside a maxtemp range if i use normal way the temp0 activates but temp1 tries to close relay at same time

thanks

two tips: 1) get it working with one temp sensor first, then scale up to 2 3 etc 2) use arrays where possible to simplify code
