Abstract: In an earlier paper the authors established the existence of Cameron and Storvick's function space integral $ {J_q}(F)$ for a class of finite-dimensional functionals $ F$. Here we consider a space $ A$ of not necessarily finite-dimensional functionals generated by the earlier functionals. We show that $ A$ is a Banach space and recognize $ A$ as the direct sum of more familiar Banach spaces. We also show that the function space integral $ J_q^{{\text{an}}}(F)$ exists for $ F \in A$. In contrast we give an example of an $ {F_0} \in A$ such that $ J_q^{{\text{seq}}}({F_0})$ does not exist.
