I'm unable to get the following EM script to work in 3.x but it works fine in 5.x - appreciate very much any ideas you all might have why!:

In 5.x the question type is equation, display:none, mandatory but in 3.x the question type is short free text, display:none, mandatory.

A javascript console dump suggests TOKEN:ATTRIBUTE_1; TOKEN:ATTRIBUTE_2 and defaultExpiryDays are populating successfully
 

The expression don't seems to have specific part for 5.X

But : with short free text question type : you don't fille answer. Equation quetsion typoe fill answer.

Can you explain what you want.

Sorry,
why are there different question types?
Usually you want to store the result of this into a variable (the QuestionCode).
And therefore you use a question of type "equation".
If you want to enter this result into a question of type "short text" you might enter the equation into the default answer.

So we don't exactly know what you want to do with that equation.

Thanks for the speedy response Denis.

In 5.x the script works as expected but in 3.x the script produces an empty result. I don't understand why...

The script is designed to produce an expiry date, measured in length of time:
- It returns a 'never expire' value of 365 x 5 days if TOKEN:ATTRIBUTE_1 is to "Yes"
- It returns a a custom expiry date if TOKEN:ATTRIBUTE_2 has been set for the particular participant
- Or it returns defaultExpiryDays if the other variables aren't set

It works just fine in 5.x but in 3.x returns an empty value.

Expression Manager parses the script correctly.

Thanks Joffm

If I'm correct only 5.x contains the the question type "Equation"?

In which case I need to use another type in 3.x (ie short-text?)

EDIT: Your suggestion worked many thanks! - just needed to put the script into Default Answer. Been working with 5.x for too long forgot how it worked in 3.x!

The question type equation exists since 2.0x if not since 1.9x. So there is definitely the question type equation in LS 3.x. No need to use some other question type than equation.
