! Package biblatex Error: Conflicting options (maxcitenames/mincitenames)

Question

I am new to Latex and I am using ieee style with biblatex but i want the maximum in-text citation when i mention the authors name directly to be as follows.

if two authors: intext citation =author A + author B +year if more than 2 authors: intext citation = author A+et al+year

I and using maxbibnames=10, maxcitenames=2 but i get this error ! Package biblatex Error: Conflicting options(maxcitenames/mincitenames).

please see MWE for better understanding.

\textbf{example 2} for this example i  just want the number to appear in the text and it works fine \cite{Dennis2014overview}.

Desired output As pointed out by Leung and Caramanna (2014) [1], the success of deploying CCS bla bla bla bla...... A public survey by Wallquist et al (2012) [2] showed that peoples preference for bla bla bla.........

for exmaple 2 the ouput is perfect. = for this example i just want the number to appear in the text and it works fine [1]

Answer 1

The golden rule when it comes to min/max(bib|cite)names is that min(bib|cite)names cannot be greater than max(bib|cite)names.

The defaults from ieee.bbx are

\ExecuteBibliographyOptions{
  maxnames = 999,
  minnames = 3,
}

So you can't set max(cite|bib)names to a value less than three without also redefining min(cite|bib)names.

Try

\usepackage[style=ieee, maxbibnames=999, maxcitenames=2, mincitenames=1]{biblatex} 

This displays (probably) all authors in the bibliography (instead of your 10, but you can of course go with 10), and it uses one or two names in citations.
