Re: [libreoffice-users] List box not updating field with bound value

Hi :)
Hopefully this is in Base rather than Calc.  The 2 tables need to be connected 
by some sort of relationship.  I don't think spreadsheets work as relational 
databases?  One of the 'obvious' 'easy answers' (and therefore most commonly 
missed)  is if the relationship is not defined in Base.  It might be defined in 
Access but it's worth checking that Base shows the same thing.  

Thanks and regards from
Tom :)

Are you using Calc or Base??
And do you automatic initialise the form ore do you use a macro to initialise 
the form and fill it with contents?

It would bee much easier to help you if you put the document online, so 
everybody can test it and see what is the best solution for your problem
1.There is a big difference between MS Listboxes and LO-Listboxes.
In MS you can address items in a list-box by there key number, in LO only by 
there name.
2.You can connect a simple macro to the "list-box-change"  event that updates 
the master table field.

I'm not sure, if my suggestion is really what you want.
