Using math operators to manipulate output value of an S-Tag (in an Email)

For this, you'll want to use the RPN tag S130 (see the wikipedia entry on Reverse Polish Notation for a more painfully detailed explanation).


Your first example would look like this:


[[S130:[[E120:dc:giftAmount]] 100 *]]


This pushes the gift amount and the value 100 into the stack, and the * operator multiplies the previous two items in the stack.


To add two values, then multiply the result by 100 (ex. (5 + 3) * 100), you'd write:


[[S130:5 3 + 100 *]] => 800


This pushes 5 and 3 into the stack and adds them (the result becomes the next value in the stack), then it pushes 100 into the stack and multiplies the previous two items in the stack.


Complicated stuff, but super useful once you get the hang of it!


Your second example is easier and doesn't require RPN, Just write "[[S120:dc:donFormId]] of CampaignB" without the + and it will render the string, "donFormId of CampaignB".


Edit: Note the warning in documentation, "The S130 Tag is intended for Blackbaud internal use only; use at your own risk". Improperly formated RPN notation can do VERY strange things to your page/email, and even cripple your ability to edit content if it breaks the admin interface. The tag above for your first example should be fine though. Basically, don't experiment with RPN on live pages and use versions wisely. Also do live donation tests for autoresponders to make sure everything renders correctly. Sometimes the donation test functionality doesn't give you a completely accurate result for special stuff like this.

John Miller:

...wanted to note one thing, on the first example, I think the E and the S need to be switched so the S120 is evaluated, then the E130.
