[Xerte] Re: Xerte 2 : Combo box value is defaulting to "" why?

[Kemp Johnathan]

Taking the spaces out of the combo box options makes no difference. The data
values already contain no spaces in my example.

I will be unavailable to reply to further emails for a few hours, but will
check in again later today.

Kind regards

Johnathan
