Select single value from csv string

Hello,

I am using SQL Server 2000.I have a stored procedure that accepts (among other things) a varchar csv string, values that come from an asp multi-select list. In the sproc, i need to set a variable if that csv string contains a specific value. I have a tally table to parse the csv into individual rows but I am yet unable to get it to work

As an example: let's say that the csv string = 'homer, bart, moe, milhouse, apu'
I need logic that will set a var (bit) to true if the csv string contains 'moe' and false if it does not.

Please let me know if additional information is required. Thank you in advance!

like this:
declare @b int
select @b = count(*) from dbo.ParmsToList(@your_csv_string, ',') l where l.Value = 'moe'

Does the value have to be in the specific column, I assume it does.

The value I am looking for will not necessarily be in the string. If it is then my var (i.e. @varMoeExists) should be set to true otherwise, it will need to be false.
