Experience Builder - building expressions

[HelenCooper]

Hi, 

I'm trying to use a button to link to a URL and pass a value from a data source.  I'm struggling to find any documentation on how to do this, and my random guesses at how to build the expression are not fruitful!

Could anyone point me in the right direction?

Many thanks, 

Helen

You have to put that first bit in quotes.

"https://mapitout.co.uk/" + {globalid}

Thank you @jcarlson , that sorted it - really appreciated!

I'm trying to build an expression that will include multiple field values based on selected map features.  So it would look something like: https://mylink/....objectids=186,171

So far what happens is my string only takes the last objectid of all the features selected. is this possible?

@rachelm - did you ever figure out if this was possible?

You can include multiple attributes with the plus sign.  The Expression below gets the lat/long from the attribute and links to google maps walking directions.

Can someone tell me what the language is for these expressions, so I can find some documentation for it?  It doesn't appear to be Arcade.
