Hello Could it be, that you submit more then one parameter with the name selected?
I tested your code with ?selected=12&selected=13 And then geht the same error, because Active4D creates an array from selected. a4d.debug.dump collection (_query) // will return selected [0] {"", "12", "13"} Regards, Oliver > Am 13.04.2017 um 06:05 schrieb Justin Will <jw...@willwerks.com>: > > Apr 12 18:52:45 Active4D: [error] An operation on incompatible types was > attempted: /F/a4dweb/50000/includes/programStandard.a4d, line 26 > > Apr 12 13:51:23 Active4D: [error] An operation on incompatible types was > attempted (expected a numeric expression or a text expression or a boolean > expression): /F/a4dweb/50000/includes/programStandard.a4d, line 27 > Apr 12 13:51:23 Active4D: [error] An operation on incompatible types was > attempted (expected a numeric expression or a text expression or a boolean > expression): /F/a4dweb/50000/includes/programStandard.a4d, line 27 > Apr 12 14:27:46 Active4D: [error] An operation on incompatible types was > attempted (expected a numeric expression or a text expression or a boolean > expression): /F/a4dweb/50000/includes/programStandard.a4d, line 27 > > Here's the lines of code called out as erroring. > > $vtProgID:=_query{"program_id"} > $vnSelected:=Num(_query{"selected"}) > > The following declarations are slightly above the assigments. > > C_Longint($vnSelected) > C_Text($vtProgID) > _______________________________________________ > Active4D-dev mailing list > Active4D-dev@aparajitaworld.com > http://list.aparajitaworld.com/listinfo/active4d-dev > Archives: http://active4d-nabble.aparajitaworld.com/ _______________________________________________ Active4D-dev mailing list Active4D-dev@aparajitaworld.com http://list.aparajitaworld.com/listinfo/active4d-dev Archives: http://active4d-nabble.aparajitaworld.com/
