InfoPath Dev

 Hi, I need a little help figuring something out. I have a multi-select list box which I've disabled changes so nobody can change any values. That is until, an "Edit" button is clicked and removes the disable status and allows changes. What I would like at this point. When the Edit click event takes ...

 This is resolved. Someone suggested to add each column instead of concatenation and that worked! Thanks regardless... 

This Office Online post explains how to add a validation rule. Perhaps give this a try? https://support.office.com/en-us/article/Add-rules-for-validation-fa530b5c-419f-4c03-a85f-d7f96cb9de95

So - if you create a new blank form, and add rules, you also can't copy / paste those? That is, this is not just limited to IP 2007 forms? I have occasionally had issues with rules pasting (same symptoms you describe) - but mainly it has been when I've got a few buttons with the same name, which confuses InfoPath....

Add a validation rule - if Admission Type = "Inpatient" and Room Number is blank, display an error to the user.

 Open the form library where the form is published in Windows Explorer. In the Forms folder in the library, you'll find template.xsn. Copy that out locally somewhere.

I have 2 fields 1. Admission Type 2. Room Number If Admission Type "Inpatient" is chosen, I would like to make "Room Number" a mandatory field. Does anyone know if this is possible and how to do it if so? Thanks in advance.  

 Thanks for letting me know! I also updated the URL in my mention above in case someone doesn't read down all the way. :)
