Usage of Range for an UDF

[Guido Meng]

I’m learnig to use UDF’s and decided to modify an old code to solve systems of linear equations that I made a few years ago. When I used this code within a fixed workbook and with somewhat fixed parameters, it works fine. The problem is that I’ve never programmed any code using the Range method/property and now something makes the code stop without any apparent/obvious error. Can someone please take a look at what I’m trying to do here and tell me where I’m wrong. The code is attached with this message:



Thanks a lot……
