Getting the following InfoPath error: Only Positive Integers Allowed Error:
Followed following suggestion (well, my 2nd dropdown was already like below) and made sure it's like below. But still getting above error. Please suggest.
If you get an error that says Only Positive Integers Allowed, you're trying to save a string into a column that is expecting a number. Most likely the Sub Project drop down's value is set to a string but because the column is a lookup, it needs to be a number instead. To fix this error, right click on the Sub Project dropdown and choose Dropdown list properties. Then underneath Entries, change the Value from d:Title to d:ID. After you republish the form, the form should start saving properly.
