Change drop-down choices based on previous drop-down choice

[rosst13]

Hi. I'm trying to dynamically change the choices in a drop-down field based on what option was selected in the previous drop-down field. I'm using the following formula as my template:

if (this.getField("Drop-Down 1").value == "A"){

this.getField("Drop-Down 2").setItems([" ", "A1", "A2", "A3"])

}

else if (this.getField("Drop-Down 1").value == "B"){

this.getField("Drop-Down 2").setItems([" ", "B1", "B2", "B2"])

}

When using this template, the second drop-down is correctly adjusting what options it shows. However, after selecting an option and clicking away from the field, the field keeps reverting back to blank instead of the option I selected.

Any help figuring out what I'm doing wrong would be greatly appreciated.

Where do you use code?

Put it in "Drop-Down 1" as validation script and change this.getField("Drop-Down 1").value to event.value.

Hi Nesa,

The script is currently in the Custom Calculation for for Drop-Down 2.

I'm pretty new to this, so I apologize for not having a strong grasp of your suggestions. You're saying I should remove this script from where I have it in Drop-Down 2 and move it to a Validation script in Drop-Down 1? And changing to event.value, would it look like this:

if (event.value == "A"){

this.getField("Drop-Down 2").setItems([" ", "A1", "A2", "A3"])

}

else if (event.value == "B"){

this.getField("Drop-Down 2").setItems([" ", "B1", "B2", "B2"])

}

Yes, try that.

Hi Nesa,

That did the trick! Thank you for your help!

Where does you use the script?
