Choice in Dropdown list determines what is put into field box

[Mark22957345xbiv]

Hi, 

I am trying to build a timetable in Acrobat DC which depends on the subject that is chosen. So in DD1M (dropdown box) you can choose from a list of subjects "maths", "english" etc. In field "1SM" I can write my own text. So it is a normal text field. 

My problem is the script for "KB". I need a script here with "what if....". If in DD1M "English" is chosen I would like the text from "1SM" to be copied into KB. However, if the choice of the dropdown "DD1M" is "Maths" I would like the text from "1SM" to go in Box KB1 not KB. 

Could someone help me with the script? I am new to this and can't figure it out.

Move your code to be a Calculation script, and change the last line to:

event.value = KB;

Also, you need to declare the KB variable, so add this to the top of your code:

var KB = "";

Unfortunately those changes didn't do the trick. The value in KB or KB1 doesnt change at all. So nothing happens, even though I posted it into the calculation script.

Here is a picture of what I changed

What is the name of the dropdown field?

Please check the Console Window (Ctrl-J) for errors. It looks like, as Bernd suggest, the dropdown field name is incorrect in the script (on first line).

You must only use straight quotes in your code, not curly ones.

Details!! Good catch, and a very common error!!

[Mark22957345xbiv]

That's it. It was the curly quotes that sneeked in there. Now its working perfectly. Thank you very very much everyone for helping me with this.

Use calculation scripts at the fields KB and KB1.

You can read some general info on Acrobat Form Scripting here:

And specifically about calculation scripts here:

Since the action is being driven from a single dropdown. I would suggest using the validation script on the "DD1M" dropdown to set the values  of "KB" and "KB1".  That is, unless the logic on this form is more complex than described. For example, what does the "DD2M" dropdown do?
