InfoPath Dev

Is this happening on the browser or client? If browser, what browser are you using? Did you try inserting the text box in a container table/section?

1) Create a validation rule that goes something like if string-length(concat(firstName, " ", lastName)) > 20 then display error "Cannot be more than 20 characters" 2) Similarly you can also create a rule that checks for individual special characters, but this would be a little more hard coding.  Perhaps an easier way ...

Filtering the dropdown when it appears more than 4 times is a little trickier than your traditional filter rule.  Maybe what you can do is create a secondary repeating field that you can add entries to when the count for that value is 4 or more.  Then you can apply this field to your filter.  If you know there are x number of ...

As far as I know, there is no way to do this with the people picker control itself.  You would have to split up the fields into their own separate controls to do this.

Looks like the average function only allows up to 30 parameters: http://office.microsoft.com/en-us/sharepoint-foundation-help/average-function-HA010379927.aspx If you know it will always be 31 days, you could try adding up all the fields then just dividing by 31?

Rules are usually triggered when a field changes.  It is then important to keep in mind when you want the rule to fire because this will dictate which field to place your rule on. From your description, sounds like you need to move your rule from the Cost field to the Item field because after the user selects the Item is when you want the ...

Glad to hear that solved your problem!

Unfortunately I don't think this is possible.  InfoPath doesn't have many different ways to manipulate print pages.  You could create a print view and then optimize for printing.  Keep controls as fixed width so that when printed its shows up as expected.

You can use rules to create this effect, though it may get a little complicated.  You can use string functions (substring) in InfoPath to parse our the hour and the minutes.  Then you can add to the minutes based on the total amount then divide by 60.  The result should be added to the hours and then the remainder should be ...

Its difficult to pinpoint exactly what the problem is without looking at the xsn itself.  I would recommend removing as much as possible from the form till you get into a state where your form can publish.  Then slowly add more and more stuff to the form and publishing each time.  When the publish breaks, then you'll have a ...
