变量赋值不起作用

I have developed a power meter and turbine control using the PIC32MZ. This has had many problems but recently thing have been going OK. I have been asked to change this it incorporate a power limiting functionality. So I created a function and called it from my ParseData(int DataSet) function.
                To make things easier I collect my data into one element of an array while I am parsing the already collected data in the other array. Data is collected from six ADC ports under ISR control and timer to trigger.
                When I wrote the limiting function, it had two ways of limiting the turbine export, first was just a Cap set to maximum permitted. The second was derived as a function of Grid voltage. This seemed to work. I have now been requested to implement an export limed as a result of high grid frequency this is where things have gone wrong. AS IO changed the frequency I was getting a random firing of the load bank.
                In trying to debug I get very strange results. Which I have traced back to two simple errors.
                When I pass the int into limit function
void LimitExport(int DataSet){ // called once every grid cycle

                The DataSet is reported as out of scope but only after the first line in the function. I use this as an address to which array element I can use as the other element is being updated by the ADC ISR. I then made a global var and saved the past value to it, now the debugger can see the proper address. Now I use the new grid values and each time through the loop add them to accumulate 11 readings. On the 11 time through the loop I divide the accumulated values to get an average.
To help with debug in previous section a make Turbine power equal to 1100. To help debug I changed the += to just = and as you can see the assignment
    PhaseAveragePower = (GridParamiter[1].ActivePower); // total power in in 0.1kW steps
never happens. I can single step through the code or set brake point after assignment but the PhaseAveragePower has a different value to GridParamiter[1].ActivePower

I have tried declaring variable as static but this did not help

Can you possibly give me an idea of what to try?

I tried uploading picture from debugger screen but got this error below so typed it in.
Line of code
    PhaseAveragePower = (GridParamiter[1].ActivePower); // total power in in 0.1kW steps
Break point set after above line of code
I Get
PhaseAveragePower  "Address = 0x8000042c, PhaseAveragePower =25067"
GridParamiter[1].ActivePower "Address =0x800025f4, GridParamiter[1].ActivePower = 1100"
