Hello all, 

I have browsed many forums but was unable to find anything.

I would like to ask for help with this problem:

I have checkbox with integer values (unchecked 0, checked 15). I need a text (textbox) with description text appear elsewhere in the form when the checkbox is selected. I need to have same textbox with varying text based on how many checkboxes are selected (i.e. when I have one checkbox, there's some text, when I have two, three selected, the text changes with them)

Thanks for any insight,

Michael

 Thank you! "Set a field value" does exactly what I want to do, but my another problem is that I have several lines of text I want to appear in the textbox and it seems that "value" field can accept only limited number of characters :/ is there some workaround?

thank you for your time!

Michael

Either set the multilines of text property from the textbox properties or use Rich Text box.
