Sorry I messed up the quotes in retyping:

m.typefilt = "INLIST(a09macct.typegroup, 'CASH', 'BANK')"
m.typefilt = "typgrp(a09macct.typegroup, 'CASH', 'BANK')"

>The both lines give "syntax error".

>m.typefilt = "INLIST(a09macct.typegroup, "CASH", "BANK")
>m.typefilt = "typgrp(a09macct.typegroup, "CASH", "BANK")
>

What's your actual code?

>>This above works well. Now I ended up with a requirement wherein the typegroup can contain a word and not necessary at the start of the field. So I wrote a udf to tackle the same which just does a $ for each and every parameters passed to the UDF so the inv. button call changed to:
