While loop - infinite calculation - reason?

[dcompel]

Hello,

My name is Daniel and I would like to kindly ask you for help with while loop. The problem is that i cant calculate this loop because it looks like it never ends. Any ideas why? Can somebody look at it for me please? Here's my code:

And here is how it should work step by step

Its hard to debug a picture!

Please post the worksheet.

You can do so by clicking "Use advanced editor" at the upper right. Then you get at the lower right an option to attach files.

EDIT:

Maybe its simpler than I thought.

You use variables "sigma.com.ed.1" AND "sigma.com.ed1" in your program. Guess both should be the same variable and the dot before the 1 is a typo.

Anyway, "sigma.com.ed" and "sigma.com.ed.1" are use as condition in the while loop but both never change - that explains the endless loop.

Oooh my GOD , you are right! thank you very much. saved my day. this is just stupid... Im just laughing right now its every time thing like that. btw I forgot to upload the file but it doesn't matter anymore.

Heres the working code (there was also mistake in condition)
