Hi people.
I have two tables, main and second.
I want to put in main tables an yes/no field, and when you put yes to that field, i want that specific data show in second tables.
How can i make this?

add the field to the table , ex: Show2nd as type YES/NO.

on the form where you show main data and a subform to show Second data.
in the form in the ONCURRENT event put
me.child.visible = me.Show2nd.value

Hier is database, please help me. Main tables are probe stocks, and ther is field Measurment. If this field is checked, then in tables stiffnes testing need to show all chips which need to be measurment. Something like this, selec from probe stock chip, where measurment = yes.
