Can I auto populate criteria for a query based on a form?

I have a form with command buttons. The command buttons run update queries.
I want to update a table with criteria from my form (LabIDNumber). Is there
anyway for the query to pull the LabID from the form that is currently active?
Thanks for help.
 
Gretchen,

Sure. Put a reference to the form control in the criteria row of the query:

= Forms!YourForm!YourControl

Sprinks
 
Humm...this did not work. When I put this on the criteria first of all it
automatically reformats the criteria and I loose the "=" sign. When I hit
the control button it runs the query but asks for parameters for "LabID" -
the field I"m trying to get the query to know from my form.

Thanks in advance for your help.
 
Use something like the following in the update query to refer to the value in
the form:

[Forms]![FormName]![LabIDControlName]

IOW, modify the update query where the Update To: section contains the above
expression where appropriate.
 
That was supposed to be in the Criteria section rather than the Update To:
section.

Sure; use a criterion like

[Forms]![NameOfYourForm]![NameOfSomeControl]

Gretchen,

I've tried to duplicate your results but have been unable to. Perhaps we're
using a different version. In any case, try:

- Verifying that the column in which you're entering the criteria is the
field to which the referenced control is bound
- Add delimiter brackets around each specifier, in case your form or control
names have spaces:

= Forms![Your Form]![Your Control]

If this doesn't work, please post:
- the name of the query field in which you're trying to add the criteria
- the name of the form
- the name and Control Source of the form control that has the matching data
- the full SQL of the query

Please post the SQL view of your Query.
