product over product or sum fails

it might be that the problem is in iidprod in combfunc.spad: if I understand correctly, its last line 

 */[eval(first l,k::K,i::F) for i in r1::Z .. r2::Z]

evaluates product's first argument for each value of the product variable and then multiplies the resulting list together. However, for some reason the eval fails. I was unable to find out why eval fails. A hint might be that the operation "summation" is not called anymore. I don't even know which operation "eval" is called...

Same thing for iidsum.
