tick box to tick from dropdown box selection

[billyc40784016]

Hello  I have a PDF form that I have made.

It has a dropdown box with 0,1,2,3 I would like a check box to tick if 1,2 or 3 is selected.

Could someone please help me

What are the names of both of those fields?

Thanks for your reply

It is actually a checklist that has 170 of these

The first one is drop-down box 1 and the checkbox A1. And so on down to 170

So the drop-down field is called "box 1" and the checkbox field "A1"?

If so, you can do it like this:

Create a (hidden) text field with the following custom calculation script:

this.getField("A1").tickThisBox(0, (this.getField("box 1").valueAsString!="0");
