Update Table from IIf Calculated Form Field (1 Viewer)

[xyba]

I have a form (fmERA) which is bound to tblData. In the form I have textbox (txtCentreCalc) which contains an IIf statement.

What I am trying to do is update the calculated value of txtCentreCalc into a field (Centre) of tblData but I'm unsure how to do this.

Any help appreciated.

If you can always calculate it, you wouldn't normally store it, as it means trying to capture all possible updates of the source values to then update your result field.

You can do it with vba but agree with minty , don’t store calculated values in tables, calculate when required
