What's the definition for q2? Running your code on Sage 4.6, I got this error:

sage: version()
'Sage Version 4.6, Release Date: 2010-10-30'
sage: P = 79; m = 2
sage: upbound= integer_floor(P^m * (P-1) / 10) + 10
sage: R.<q> = PowerSeriesRing(IntegerModRing(P^m), upbound)
sage: def EEbuild(bound):
....:     EE = 1 - q - q2 + O(q^upbound)
....:     for i in range(2,bound+1):
....:         EE=EE+(-1)^i*(q^((1/2)*i*(3*i+1))+q^((1/2)*i*(3*i-1)))
....:     return EE
....:
sage: lil = integer_floor(sqrt(upbound*4/3)) + 10
sage: ee = EEbuild(lil)+O(q^upbound)
