Here is another formula that should do what your formula does...Maybe you applied it incorrectly?
[Table="width:, class:grid"][tr][td] [/td][td]A[/td][td]B[/td][/tr]
[tr][td]1[/td][td]Business Mortgage, Loan[/td][td]Mortgage[/td][/tr]
[/table]
B1=LEFT(MID(A1,FIND(" ",A1)+1,99),FIND(",",MID(A1,FIND(" ",A1)+1,99))-1)
