Textbox #Error in a form coming from a Query that has not run yet.

[IStogias]

Hi All

Relatively new to Access.
I have a DLook up textbox getting a value from a query.
When i am running the query, textbox works fine and returns/display the exact values i am after.
But upon opening the form, I am getting #Error on the textbox until I run the query.

Is there a way when I open the form to dismiss this #Error showing in the textbox?

You’re seeing that error because the form is trying to display the DLookup value before the query it depends on has actually run. One easy workaround is to add an Nz() or IIf(IsError()) wrapper around your DLookup, so Access shows something blank or default instead of the error.

That usually happens because the form loads before the query has any data to return, so the DLookup evaluates to an error. You can avoid showing error by wrapping the DLookup in Nz() or an IIf() check, for example returning an empty string or 0 when nothing is found. Another option is to refresh or requery the form (or control) in the form’s On Load or On Current event so the query runs before the textbox is evaluated.

Usually that happens because the DLookup is trying to evaluate before the query or referenced control has valid data. A simple fix is to wrap the textbox control source with Nz() or an IIf(IsError(... )) check.

Something like this often works:
=Nz(DLookup("Fi eldName","YourQ uery","Criteria "),"")

That way the textbox shows blank instead of error speed stars until the query has data available. You can also force a Requery on form load/open if needed.

When a Microsoft Access form displays “Textbox #Error” from a query that has not run yet, it usually happens because the textbox is trying to calculate or display a value before the query has returned any data. This issue can be fixed by checking the query execution order, using proper error handling such as Nz() functions, and ensuring the form loads only after the required data source is available.

A Textbox #Error appearing in an Access form usually means the textbox is trying to display information from a query before the query has finished running or returned any records. zz0.n2jwdb9v7lg zz

When building a match replay platform, technical errors can affect the viewing experience, and the “Textbox #Error” message usually appears when a form tries to display data from a query that has not been executed or returned results yet.

A smooth viewing experience depends on reliable data loading, and the “Textbox #Error” issue often appears when a form tries to display information before its connected query has successfully run.

To clear that #Error on startup, update your text box's Control Source to wrap the DLookup inside an IIf and IsError check, like =IIf(IsError(DL ookup(...)), "", DLookup(...)), or point the function directly to the underlying table/query using proper criteria rather than an unquery's temporary state. An even cleaner fix is to calculate the value during the form's On Open or On Load event using VBA to populate the text box only after confirming the source query has executed.

This is usually related to the order in which Access processes the form and its underlying data. If the textbox is evaluated before the query has returned a matching record, DLookup has nothing to work with and can produce an error. A good approach is to provide a fallback value instead of allowing the expression to fail. For example, Nz() can be used to return a blank value or zero when DLookup does not find a result. An IIf() condition can be used for the same purpose if you need more control over the logic. It’s also worth checking when the lookup is being executed. If the form depends on a query that has not finished updating, run a Requery or Refresh from the form’s On Load or On Current event. This makes sure the data is available before the textbox tries to evaluate the lookup expression.
