Please help!



Got a few days left and I need to model a random effect of species on the body mass (logM) and temperature (K) slopes. This is what i've done so far that works:
    model1<-lme(logSSP~logM + K,random=~1|species,data=data1)
    model2<-lme(logSSP~logM + K,random=~K|species,data=data1)
    model3<-lme(logSSP~logM + K,random=~logM|species,data=data1)


The one I now want is:
    model4<-lme(logSSP~logM + K,random=~logM|species,K|species,data=data1)
    #I need the random effect of spp on both slopes of logM and K, but this code doesn't work so how do i change the code??????
    :( Any help will be greatly appreciated
