// degree0 = "bottom"; degree0 = "top"; 

thanks! yes! (ithis works!) ("undef" must be in the instruction) // degree0 = "bottom";degree0 = "right"; deg0 = (degree0 == "left")  ?   0  : (degree0 == "top")      ?  90   : (degree0 == "right")    ? 180   : (degree0 == "bottom")   ? 270   : undef;  echo(degree0, deg0); Can not understand how this would add anything .:(I get an error message) //degree0 = "bottom";//degree0 = "top";degree0 = ""; deg0 =  (degree0 == "left")   ?   0      : (degree0 == "top")    ?  90      : (degree0 == "right")  ? 180      : (degree0 == "bottom") ? 270      : deg0; echo(degree0, deg0); Den söndag 27 mars 2022 13:38:15 CEST, Michael Frey <michael.frey@gmx.ch> skrev: On 27.03.22 12:19, Jan Öhman via Discuss wrote: Tried a bit, but failed // degree0 = "bottom"; degree0 = "top"; // if (degree0 == "bottom") deg0 = 270; // if (degree0 == "top") deg0 = 90; // degree0 = "bottom" ? deg0 = 270; // degree0 = "top" ? deg0 = 90; degree0 = "bottom" ? deg0 = 270   : degree0 = "top" ? deg0 = 90; echo(degree0, deg0); How about? //degree0 = "bottom"; degree0 = "top"; deg0 = (degree0 == "bottom") ?  270   : (degree0 == "top") ?  90 : undef; echo(degree0, deg0); or maybe //degree0 = "bottom"; //degree0 = "top"; degree0 = ""; deg0 = (degree0 == "bottom") ?  270   : (degree0 == "top") ?  90 : deg0; echo(degree0, deg0); It is hard to guess what you want to do when degree0 is neither top or bottom.
