Do you understand the code you have and what a struct is?
for this error
you need to print the attribute of your structure
Serial.print(RemoteXY.value_01);
Exactly as you did for the text_1 attribute (weird names by the way - why not simply value and text) ?
Also if the values are integers, don't use dtostrf() - you can just use snprintf() or itoa() and the likes
