InfoPath Dev

For example:
I have secondary datasource "Numbers" name Numbers, wich contains two columns: Title and DocID.
I want to my field named "Field1" had default value equals some data from "Numbers", belongs on wich DocID I will pass. For example (I write it in SQL):

SELECT Title
INTO FooVariable
FROM Numbers
WHERE DocID = :myValue

Then: Field1.DefaultValue = FooVariable.
Can I do this with XPath ??? If so, how?

Hi Ekzarov,
Have you looked at using filters to do this? Certainly you can use Xpath as part of your condition in your filter. Filters are a much discussed forum topic and Greg has written several HowTos on it as well. Please search the forum for related posts (top right) and the site for the HowTos (top left)

I'm not sure I understand your issue. Sounds like you are using a default value formula--if not try that.
