Form-Multiple record: field date, on change,all dates below must take same value

Applications Forms
#1

I have a Multiple record form, which in insert mode appears as follows:

serial number|Date|Name|Amount…
serial number|Date|Name|Amount…
serial number|Date|Name|Amount…
serial number|Date|Name|Amount…
serial number|Date|Name|Amount…
serial number|Date|Name|Amount…

The fields must be filled in with data.

I would want this:

When i change date in row2, row3,4,… will change (row1 will not change).

Thanks for helping.
