SPSS does not have a built-in function to calculate the difference between two percentages from two independent samples. This calculation must be done manually using the formula:(p1 - p2) / sqrt(p1 * (1 - p1) / n1 + p2 * (1 - p2) / n2)where p1 and p2 are the two percentages, and n1 and n2 are the sample sizes.
