Multiple if statements in expression

[Qlik_ULG]

I am building a large complex expression to calculate some total figures, but it seems as if a null value, or 0.00 amount breaks the expression down the line. I am not sure where. Each expression follows the same pattern but adds on another line each time.

I'll try explain it in pseudo code.

I have my base calculation  which sums some columns to get a total figure. they are the base costs.   

     then add some additional charges to these costs. (a simple if charge type =1, then rate)

               then calculate an additional charge when can either be a flat amount, or a percentage of the previously calculated total +                additional costs

                    then calculate a discount on the new final amount, which again can be a flat fee or percentage based on the new                     total.

                        the finally a complete total, which is just a total minus the last charge

I have tried building it step by step, but generally fall at certain hurdles. I can calculate the additional charges separately but when I try to add them together, it somehow breaks. I think my if statements may be out, or not have enough.

Any advice on how to build this?
