use respondent e-mail to re-send questionnaire

Question

I am trying to program a single questionnaire as to be sent to participants in two waves. I tried to use the mailResume command but I need an id for the category "mailing" and I can't find it (you activated the mailings function but cannot find any code I could include in the syntax):

mailResume(caseSerial(),XXX, 1 * 3600);

Also, I do not get quite well how this can be used in combination with the buttonHide function...Could you help me out?

On another note, I tried to center the images I inserted for my experimental treatments and include commands such as "margin" but the button "next" is still too far below the image...any clue how can I fix that?
Thanks, Laia

I need an id for the category "mailing"

Please create a mailing in Invotation Mailing -> Mailings.

When stored, you will see an ID for this mailing in the above menu.

Also, I do not get quite well how this can be used in combination with the buttonHide function...

Well, the manuel Example: Pause Between Survey Waves gives a start. Could you possibly specify your question a bit further?

Depends on how you embedded the image. Please feel free to add some HTML code to your question.
