[Mishi2658259020w6]

I need your help, I want show and hide fields via dropdown menu based on values, I tried alot different methods but didn't achieve perfect results. Thank you in advance for your time and consideration.

Code I used here............

if(event.target.value <30){
this.getField("TT534").display = display.hidden;
this.getField("TT5checkeuoruk3").display = display.hidden;
this.getField("TT542").display = display.hidden;
this.getField("TT543").display = display.hidden;

}
else{
this.getField("TT534").display = display.visible;
this.getField("TT5checkeuoruk3").display = display.visible;
this.getField("TT542").display = display.visible;
this.getField("TT543").display = display.visible;

}

Script in that file refer to fields that doesn't exist.

From your first script if you use it in the dropdown field make sure 'Commit selected value immediately' is checked.

Yes, Commit is selected but its not working smooth way, I attached a screen recordrd video.

Use script as 'custom calculation script'.
