SPI Arduino Slave transmitting data

hi,
first of all thanks for the great blog on SPI communication between Arduino as a slave and master. i run you code "How to make an SPI slave" successfully which given in the link http://www.gammon.com.au/forum/?id=10892
in this example SPI Slave Arduino receive data from Master and transmit it serially but in my project i want to transmit data from several Adruino SPI Slave to Master and then Master Arduino will transmit it serially. i search a lot on this topic but did not find any material , if you could help me i will be very thankful.

To save me supporting this code on two sites, please post your question to the Arduino forum:
