Hi as depicted below you need to have a certain inputs and outputs to your inner operator for a MapFoldwi iterator depending on the number of acculumators specified. (default: 1 accumulator)

In this example sketched above it is assumed that you want to have
2 accumulators and
2 input arrays as well as
1 output array
for your MapFoldwi iterator.
Then your inner operator needs to have the following inputs and outputs:
Inputs
i (index) integer-type
acc1_in (1st accumulator) pre or user defined datatype 1
acc2_in (2nd accumulator) pre or user defined datatype 2
Element (1st input array) pre or user defined datatype 3
Element (2nd input array) pre or user defined datatype 4
Outputs
continue (continue condition) bool
acc1_out (1st accumulator output) pre or user defined datatype 1
acc2_out (2nd accumulator output) pre or user defined datatype 2
Element (1st output array) pre or user defined datatype 5
I think that there might be a mismatch of your input/output structure of the inner operator. But in order to check this more information would need to be provided by you, at least the input/output structure of you inner operator.
Please also refer to the SCADE User Manual -> Designing with Iterators -> Definition for MapFoldwi Iteration Pattern.
