howdy boys and girls:

i've made some headway in creating my tree, but am now having trouble printing it. I would like to make sure i'm constructing it properly. based on this input from a file 1(2,3(10)),4(5(8),6(9),7) i'm looking to verify getting 1 @ root 2 @ roots left and 4 @ roots right, and subsequently print out the rest of the tree. as of now its telling me my PrintInOrder is not a member of my class.. included is all my source. analyze the PrintInOrder for suggestions..thanks for your time

file is attached
