Help with Physics -- calculating current in circuits with resistors?

That's the diagram
http://www.webassign.net/giancoli5/19_38.gif

Determine the magnitudes and directions of the currents through each resistor shown in Fig. 19-38. The batteries have emfs of e1 = 9.0 V and e2 = 17.0 V and the resistors have values of R1 = 15 , R2 = 20 , and R3 = 25 .

I already current at R2 = 0.412903 A, R3 = .34968 A.

Logically, R1 should be around 0.05 A according to the loop rule... but it says it's wrong on WebAssign. I only have one try left, so can anyone tel me what I'm doing wrong?
