When defining the values of suma[x] as regression function I 'm able to obtain te true values of suma[x], when entering x manually.

Nevertheless when I try to Nminimize suma[x] it seems that this finction does not take the value of x

I willl thank a lot any suggestion

I Remove the Quiet[]. When something is not working we want to see all warnings.

That shows there is a 1/0 problem that should be tracked down and fixed.

Next there are warnings about inexact, but I think those can be ignored.

Next it prints "Hola Null"

That goes away if I change Print["Hola ",x;]; to Print["Hola ",x]; But then it only prints "Hola x"

You print "pHcalc { Log[H$257549]/Log[10],..." and that is possibly an an issue related to local variables inside of a Module.

If I remove the use of Module then the H$257549 are replaced with H.

Next there are lots of errors about "not a number" when x is negative. Those need to be tracked down and fixed.

Can you reproduce all those warnings and errors?

Can you see the reason for any of those and perhaps see a way to fix one or more of those?
