Problems with value lists

[sdcg]

Hi all,

I am a beginner FileMaker user and I am a little bit lost.

Any help will be apreciated.

I have two tables: software and versions.

Software table has two fields: sw_name, sw_description.

Versions table has 5 fields: Name, description, date, file and

sw_name.

I have created a simple relationship between this two tables with

sw_name as matched field: 1 version is related to a specific one

software and a specific software has N versions.

Then, I have a layout with 2 value lists: Software value list, and

versions value list. Software list is defined with "include all

values", and versions value list is defined with "include only

related values starting from table software".

In theory, when I select a value from software list, value list

SHOULD be updated with the versions for that software, shouldn't it?

Ok, this is working only for the first value in the list. I can see

that versions list has the correct values, but then when I select

another value from software list, in version list appears: <no values

defined>.

I know that there are versions values for that software.

What am I doing wrong?

Is that, the layout needs to be refreshed? Is there any form for

performing an script when event: onChange is detected in software

list? Furthermore, FileMaker allows event handling?

I know, a lot of questions, -), but as you see I am totally lost.

Thank you very much,

Silvia
