Using macros with multiple users of database?

So long as the users have distinct front ends w/ their own copies of the macros and queries, THAT part won't be the problem. However, if they're trying to update the same records at the same time, THEN you run into locking issues. This'll be dependent on what model of locking you actually use (row/record, block, table, which get progressively more challenging to write across). If each user is limited to use the macro/query on the record they're currently on, however, and you don't let two users edit the same record at once, it should do ok. Worst case then is a "someone has changed this record since you began editing it" sort of message.

My question to you, however, is if the calculations are being done for the sake of the form, and not for reporting or data storage, why are you making them via macro instead of formula or function to display on the form as needed? For example, if you're showing the extended price based on a quantity and unit price being entered by the user, make a text box that has as a control source the formula "=[QtyField]*[UnitPriceField]" instead.

Macros should almost never be used in a database when code or formulas can be used instead.

Thank you Rachel -
the reason I'm using the macros is that I have 5 fields that are entered in by the user as either X, T, or A - the "A" stands for "Absent" -

The macros consists of a series of queries assigning a value of "1" to each "A" and then totaling them - would I be able to do that portion right in the form? If so, I would rather do it that way. I couldn't figure out a way to do that using a formula right in the form.

thank you

thank you so much - that is EXACTLY what I needed!
