This is kind of what I was looking for, apart from it is checking the Model Grade against itself and not the Typical standard grades. The Model grade on SDEDATA_Checking wants to compare with the typical Standard grades grade on QA1001, and depending on the profile prefix depends on which grade it compares to in the table. The explanation tab just had everything on one sheet to help with the explanation of what I am trying to achieve.

If the profile starts with UB, UC, EA, UA, WB, WC, or PFC then this makes it Hot Rolled Steel, which means the Model grade wants to compare with the Hot Rolled Steel Grade from the "Typical Standard Grades" table (QA1001 Tab), If it matches then return Yes, is not then No (True or False will also work for me too)

Sorry if I did not make this clear
Cheers
