I want to incentivize my survey by offering a coupon at the end of the session. I would like that coupon to be valid for X days which would mean calculating a date that is X days in to the future. Can that be done using one of the expression functions?

Thank you all

This expression will give a date 7 days from present (the 604800 is the number of seconds in 7 days):

Is there a special way to insert this? When I do this, this appears:

< / span > < spanstyle="color: rgb(153, 0, 0);" > date < / span > < spanstyle="color: rgb(0, 153, 0);" > ( < / span > < spanstyle="color: rgb(0, 0, 255);" > 'd/m/Y' < / span > < spanstyle="color: rgb(51, 153, 51);" > , < / span > < spanstyle="color: rgb(153, 0, 0);" > time < / span > < spanstyle="color: rgb(0, 153, 0);" > ( < / span > < spanstyle="color: rgb(0, 153, 0);" > ) < / span > < spanstyle="color: rgb(51, 153, 51);" > + < / span > < spanstyle="color: rgb(204, 102, 204);" > 604800 < / span > < spanstyle="color: rgb(0, 153, 0);" > ) < / span > < spanstyle="color: rgb(0, 153, 0);" >

It is inserted as any other Expression Manager expression. Here's a sample equation type question:

You can't insert this via the WYSIWYG editor, you need to write it into the source code / plain text view.
