I have made a few modifications to your snippet to create a new folder or record to an existing folder.
I am attempting to get the date and time of session inserted into the expression evaluator.
I can set up a snippet that just inserts the date into the evaluator and it works fine. But I can not figure out how to insert that into the evaluator as it is set up in the snippet.

I am not at all familiar with the workings of the object expressions.

Here is the epression as in exists.

"Session/" + (In2 == null ? In1 : In2) +"/session.edf"

I have connected In3 to Date and time from OSinfo

I have tried variation using In3 "Session/" + (In2 == null ? In1 : In2) +(In3)"/session.edf"

Every attempt ends with an error or "In3" being inserted as text

Thanks

I think you forgot to add "+" after your In3 variable.

The snippet on the link below does something similar (but only one variable so it uses In1):

Thanks.

That was a silly oversight

Works fine now

This does exactly what it should. One folder is created for each session.

I would like to have it create a session folder and append the date just prior to the .edf extension. Instead of session.edf I would like it to read date.edf

Thanks again

I went back to what I know best. I split the expression onto pieces and used text transforms with text plu variable and got the results I wanted.

Is there info somewhere about the uses of theobject expresssion evaluator. I know it functions a bit differently that the other evaluators.

It is most commonly used for more complicated text operations.

But it can do also very advanced stuff, because Object type has a wider scope (images etc.) than just text.
