Let $S_{\mathfrak{z}}(k,r)$ be the least positive integer such that for any $r$-coloring $χ: \{1,2,\dots,S_{\mathfrak{z}}(k,r)\} \longrightarrow \{1, 2, \dots, r\}$, there is a sequence $x_1, x_2, \dots, x_k$ such that $\sum_{i=1}^{k-1} x_i = x_k$, and $\sum_{i=1}^{k} χ(x_i) \equiv 0 \pmod{r}$. We show that when $k$ is greater than $r$, $kr - r - 1 \le S_{\mathfrak{z}}(k,r) \le kr - 1$, and when $r$ is an odd prime, $S_{\mathfrak{z}}(k,r)$ is in fact equal to $kr - r$.
