Connecting inputs to the function - inputs should be in the same order as they are created

[vinu1722]

A detailed bug report is written by Upi in https://labnotes.ncbs.res.in/bhalla/moose-bug-functions-controlling-reac-rates-diagnosis-and-workaround.

In short this is what happens. If you create molecules A and B in that order and then use them in a function. Then they should be connected in the same order i.e., A --> func.x[0]
B---> func.x[1]

NOT

B--> func.x[0]
A---> func.x[1]
