How to use wildcard or like command in decision stage

[Mikendersen]

How do I get my decision to read true/false if my data contains .pdf anywhere in the text. Here's a picture of what I came up with so far (it doesnt work).



Being somewhat new to BP I have problems solving expressions so are there anywhere to learn more about them?

 

[pug]

Try InStr([attachment], ".pdf") > 0

 

[sivagelli]

Try expression Instr([Attachments], ".pdf"). InStr() returns the position of the .pdf it finds in [Attachments] data item, else it returns 0.

It worked...Thank you very much for the help
