Dear Wayne
the '50839' tag problem is over but Acapella is showing different
error: "Data item not found in the current data block".
Perhaps it is not getting the 2nd page - as I am having two image for 2
channel - channel 1 for live and channel 2 for dead
thus the complete error is appearing as:
>> Command line syntax incorrect or data item not found (_["image" &
Dead_Channel]): Data item not found in the current datablock: _["image" &
Dead_Channel] <<
Thanks
