I'm still a beginner, how do I solve this error
Hi, @Achmad Anwar Annas
Based on the error message it say that a script name called "JQuery" is not available.
You can all your module script's in Interface Layer inside a script tab where below image on the bottom you can notice the scripts.
And the forge component which your are using is so old and it referring the older OutSystem script
In the image which you shared , if you notice on right side you can see (Which is a module properties) there are two scripts are added , just remove the "JQuery" the error will be removed.
thank you very much, i will try it
