I am a novice who has built a database to track vineyard spray records. I
have put a multi-select list box on a data entry form, and cannot figure out
how to get the selections made in that list box to GO somewhere. I need them
to populate to a table. Have read many posts on how to do this and cannot
find an example of code that I can work with at my novice knowlege level.
Any guru's out there want to help a noob out?

Thank you in advance!

This may be the sample code you were referring to. You will need to
change the control names, table names, and field names to match your
database; I can't help much there, because I cannot see your database.

If you try to implement this and have problems, please feel free to
post back with an indication of what specific problems you're having.

John,

Thank you so much for the sample code that you provided me. I did paste it
into my VB editor on the form I am using to enter data, and changed (what I
hope is) what I need to; names of the tables, fields & functions. I have
pasted the revised code below. When I tied this code to a macro to run, i
get the error: NO CURRENT RECORD. I have not found any info in Access help
to assist with troubleshooting. Can you see any obvious misteakes I have
made?

Thank you again!

Sorry... I didn't get back to you, and now I'm just out of time prior to going
off on a week-long trip. Please repost and hopefully someone else can help.
