InfoPath Dev

 Hi,  
I try to modify form (SharePoint 2013 Online) using InfoPath 2013 to select check-box after select item on a drop list.   
I have two lists: Clients and Job List. On Clients I put client name and select this check box's DMA, DWP, DMG.      

On Job List I want to create item only for those Clients, that have select specific check box on Clients list.

How its should work:
After create element I can choose Client from drop list - this list has reference to Client list by Name field. After I choose Client, the check box's in this form should select the same check box such as is highlighted in the list of Clients.

I have try to do rule on Client field (on Job List):   
When DMA (on Clients) = True then set field value DMA_J = True    
When DMA (on Clients) = True then set field value DMA_J = DMA (from Clients list)    

Please help. Maybe XPath can help, but I don't know this language.
 

Hi Krzysztof,

Would it be possible for you to attach a sample of your form (options tab > add attachment)? I'm sure this is possible but would like to see how your form is set up so I could give you a clearer solution.

 My form. Please check this.

Please check if this sample form is close to what you need (save the form and open in design mode).

 Why I can't ope this form? Security on domain level?

Design mode :)
