Hi Jeff,
Thank you for your response!
Here is my work:
Under Form History's Onload event, I picked the Code Builder and entered
the expression below
Me!PercentageH = Forms!frminitial!Percentage.
I always have a message that Access cann't find the frmintial (form A). I am
sure that the Initial form in the database. But i cann't call it. ??
-------------------
I also tried to insert a textbox in the History form (form B) and named it
"PercentageH". At the PercenageH's ControlSource, I entered =
Forms!frminitial!Percentage. However, I got "NAME error"
Please advice
Thank you
Chi
