While Loop indexing help.

First off, My code is 600+ lines long so I cannot post the entire script. Here is my setup for nested while loops:

count = 0;
CL=.45;
CL_IC1 = 0;
R_calc = 0;
while R_calc-20 <= R_all
    Fuel_Rat = Fuel_Rat+.001;
    count = count +1;

syms x
syms y

   while abs(CL-CL_IC1)>= .001
      CL = CL+.001;

Basically, I need the R_calc and R_all to converge for a given CL that also converges with its output. I was checking the initial calculations by hand and found some errors. The final value for the Fuel_Rat term is .4048; however in the computations shown below, it uses its initial value, which is .3578.

WS_TO = WS_LD./(1-XX*Fuel_Rat);

When I use the initial value for "Fuel_Rat" the output is identical to the work space value. Does anyone know why this is occurring? XX = .75

To narrow my question, it seems like within the CL while loop "Fuel_Rat" is its initial value. But once this loop ends, it begins to iterate. How do I fix this problem, such that the "CL loop uses the final value for "Fuel_Rat"?

You haven't posted enough of your code for us to give an opinion.

As Walter said, the code you posted is not enough.

You can check if the code updates the values of R_calc and Fuel_Rat at the end of each loop.
