datas of previous record

datas of previous record

(OP)
Hi every body.

I have a "standard" browse with a "standard" form to update/insert.(C5ee)

When I create a new record, I need to know some values of the previous record of  the file (for exemple the date "myfile:DateOestrus") to do some calcs in the form.

I try this way :

1°) put the browse procedure and the form procedure in the same module
2°) create a data "PreviousDateOestrus) in the module.
3°) assign the value myfile:DateOestrus to PreviousDateOestrus by putting the code "PreviousDateOestrus = myfile:DateOestrus" in the embed "End of format an element of the browse queue/Browse on Myfile".

It's work well but if I delete ALL the records, the  "PreviousDataOestrus" data keep the value of the last record read and don't assign to 0.

May be it's not the good embed to do that?

Could you help me?

Thanks

Hi!

Instead of this, why don't you create an ALIAS of the table in the dictionary and use the Alias table to find your previous value & calculate?

Thank you for your answser.

Yes it's an other way, but I resolve the pb by adding clear(myvariable) on embed "browse box : no record found".

But since a few minutes I have a big problème when linking :

LINK ERROR : unsupported record type1   0

I try with backup of d-1, d-2 d-3, etc ... with the same result!!!

what could be happened?????
