TOKEN:ATTRIBUTE_X is empty during survey for anonymous survey. TOKEN:ATTRIBUTE_X is related to survey, ATTRIBUTE_X is related to token ONLY when sending email and reminder.

Manual : https://manual.limesurvey.org/Email_templates#Email_placeholders

Tkey are all private, NOT ANONYMOUS survey where I have problem with TOKEN:ATTRIBUTE_X.

The TOKEN:ATTRIUBTE_X is filled with value (See Forum https://www.limesurvey.org/forum/design-issues/117048-email-template-if-statement-with-placeholder-token-does-not-work#177423) Line 5.
But the Placeholder is not usable in {if}-statement. I tried with different approaches: Either there was no output or no rendering.

I have add the Testpart for you above the current email-template for send to user:
I upload the lss file. Is this OK? For testing I did not aktivate the survey otherwise I can't change the questions in a simple manner.

I don't know why, but know there is alltime an output in the sent email. Maybe various typos in all the tests. Unfortunatelly I overwrited the old email-template and have only the images left (also published in forum). At that time there was either no output/empty «», or it wasn't rendered «if(TOKEN:ATTRIBUTE_1 == 'DU', 'TEST-YES', 'TEST-NO')».

In the current test, attached as lss-file there is everytime an output. But the "wrong" output «TEST-NO» althought the value in {TOKEN:ATTRIBUTE_1} is "DU", like in the {if}-statement for {ATTRIBUTE_1} where the output is right: «TEST-YES».

Hope this will help
