Update a field from profile activity or vis versa

Hi

could you take a look at my issue. I want to update a cb field text (cb_desc) from a cb activity (cb_ac) on profile or vis-versa.
I've used this trigger

Autoaction : Type Field

Trigger:
OnUpdateUserProfileSave

Condition
cb_ac not empty

Action
cb_ac - set value - [var3]

can you tell me what is wrong?

Use the trigger onAfterUserUpdate. If you're not using latest CB Auto Actions release were you can select the field from the dropdown then you need to be sure your field is a valid substitution by surrounding it in the substitution brackets (e.g. from cb_ac to [cb_ac]). I'm not sure what you're trying to do after that though. You want to set cb_desc to the value of cb_ac?

Yes that is what i want to do. setting cb_desc to the value of cb_ac

And is it possible to suggest hashtag while writing a post on activity?

Then you'd need to use a Field action with the following.

Field: cb_desc
Operator: Set
Value: [cb_ac]

And is it possible to suggest hashtag while writing a post on activity?

I don't see what this has to do with this current topic, but no.
