access function

[Russ]

i have a function taht i use in my access database (the same database that is
linked to the infopath document). this function brings values for patients
with multiple records in a table into one field, seperating each datavalue by
a comma. basically it gives me a list into one cell as opposed to the
mulitple records. i want to use this funciton in my infopath document. how do
i do this? is there a section in infopath to add universal functions or
modules?

thank you,
russ
