Formula evaluation failed, exchange 34344011

Question

Good  day,

I am doing a MonteCarlo simulation to consider how by varying  3 of the global parameters the result would change. When running the MonteCarlo I obtain a weird result and the following message: Formula evaluation failed, exchange 34344011 . Do any of you to what it refers?

When I go to the help log, the multiple errors that appear mention cyclic dependance. 

Thanks in advance.

When looking at the log, it says:
