I'm sure it's a great video, but since I haven't watched it, I don't know the exact details of what you set up. Does it match the method shown here?
My problem is that, I cannot find a way to have the value of the Date-field "Last Menstrual Period" from a SELECTED portal row (in the 1st portal) automatically copied to another date-field (in the second portal), in the matched set of records(portal rows).
And what determines WHICH of the records in that portal should get this value? All of them? the next new record created? One that is selected by a mouse click? (Click a row in portal 1 to bring up group and then click a row in portal 2 to set the date field in that clicked row?)
All would seem to match your description of the issue. Many of them could be made to work if clicking the row in portal 1 were to set a global variable to the contents of that portal row's date field. But how you move the date from that global variable will depend on the details of exactly what you want to see happen in the second portal.
It's also possible to drag and drop data from a field in portal 1 into a field in portal 2...
PhilModJunk, thank you for your response!
Despite the mess of my description you seem to have fully grasped the Idea. To give an answer to your pertinent questions, I would like that, the value in question being auto-inserted in every new record created in the 2nd/"slave" portal. That' s all it is! Now, regarding the portals' setup, it does actually, match your description in your link! So, like I said initially, everything I could imagine to use in order to have the value of that particular field in the selected portal row (master portal) being auto-copied in a similar field in every new record created in the slave portal, the value filemaker choose to copy is that of the 1st record in the master portal and not the value in the selected record. Although dragging n dropping the value manually (or inserting the same value again) in the target field, all look effective, you will agree they don't sound as attractive options at all, in terms of data entry efficiency. Any ideas how get it auto-copied?
Several of the Starter solutions use the following method on their iPhone layouts so that they can add a new record on a child table layout that is automatically linked to the current parent record. It should work for you was well.
Open up field options for your date field in Portal 2's table.
Specify an auto-enter calculation and specify the global variable name as the sole term of this calculation. When you click a portal row in portal 1, your script loads a variable and then each new record in portal 2 will auto-enter that variable's value when you create the new record.
The main "catch" to look out for is to be sure to always have the correct value in the global variable. In some cases, you may need to clear that variable to keep the wrong value from appearing in the field.
