Problem with Steel design with a user-defined section 1

[normm]

I wonder if anyone can see any mistake in the way I have defined the Member Property of a Tee section in the attached file.
It is a short trial analysis model file. The analysis part runs fine. But the design and stress check part does not run saying there is a mistake in the member property input.
Exactly the same file using a standard rolled section also runs fine. Also the way I have defined the tee section has been used in many Staad examples.

I will appreciate your help.

Hopefully the file is uploaded successfully now.

This time it is in Notepad.

STAAD will not do a code check on a member defined with the Prismatic command. You need to set up a User Table for the Tee section.
