I am going to take a huge leap here:  This equation does not look complete-what is C2O4 exactly....looks like some H is missing....now I may not be reading this correctly....but what are your condioions....ACIDIC OR BASIC.....makes a big difference with KMnO4...it can be done in basic media or acidic....

So I can do this....acidic medium:

+1 +7 -2   +1 +3 -2   +1 +6 -2           +2 +6 -2   +4-2  +1 -2   +1 +6-2
 KMnO4   + H2C2O2   + H2SO4 ---->    MnSO4 +   CO2 + H2O   +  K2SO4   
   
5e- + Mn+7  Mn+2 Reduction
5( C+3  C+4 + e-) Oxidation 
   
Balanced   2 KMnO4 + 5 H2C2O4 + 3 H2SO4 ------> 2 MnSO4 + 10 CO2 + 8 H2O + K2SO4
