unexpected VARSYM, ZIMPL program

Question

I am getting an unexpected VARSYM error for my ZIMPL program, I have no idea what the problem is, here is a portion of the code

Here are the variables

var FWPlus1 integer   >= 0 <= 4;
var FWPlus2 integer   >= 0 <= 4;
var FWPlus3 integer   >= 0 <= 4;

goes up to 28, with the upper bound at 3, 2, and 1 for some of the points

here is the equation that is getting the error

        FWPlus24 +FWPlus25 +FWPlus26 +FWPlus27 + FWPlus28);

the error says it is at the end at the semicolon

Answer 1

Sorry but I think I figured it out, it didn't like that I was multiplying by zero in 2 of the terms
