Mathcad: Iteration in Iteration

[tomluft]

I'd like to solve a set of equations iteratively. The problem is that one of these equations is also only to be solved iteratively.

I attached my mathcad file. The variable lamda is the one which causes problems.

I also tried to define my equations as functions with the outer iterative variable (here: d) as parameter - with no success.

see thread552-331386 for an example of using Mathcad's solve functionality.

For most things, you ought not need to make your own solver.

I already read this thread. Solving an iterative equation is not my problem.
I have an only-to-be-solved-iteratively-equation within some equations that are only to be solved iteratively.

So I have to iterate d+1 until it is equal to d and within this there is lamda+1 which has to be equal to lamda.

I found a solution for my problem. It's not the most elegant one, I suppose, but it works!
To iterate lamda within the outer iteration I built myself my own solver as a loop.
The mathcad file is attached.
