InfoPath Dev

I have a drop - down list box that gets entries from a secondary data source that I need to filter more than 5 conditions on.   I've tried using Xpath in an expression, but it doesn't seem to be seperating the arguments.  All of the arguments have 2 conditions, IE, field needs to = text, AND @field = >number.  Here's how I tried to do it -

xdXDocument:get-DOM()/my:myFields/my:SkillSet = "Lighting" and d:Lighting >= 75 or

 xdXDocument:get-DOM()/my:myFields/my:SkillSet = "Audio" and d:Audio >= 75 or

 xdXDocument:get-DOM()/my:myFields/my:SkillSet = "Video" and d:Video >= 75 or

 xdXDocument:get-DOM()/my:myFields/my:SkillSet = "IT" and d:IT >= 75 or

(xdXDocument:get-DOM()/my:myFields/my:SkillSet = "Breakouts" and d:Lighting >= 40 or d:Audio >= 40 or d:Video >= 40) or

 or xdXDocument:get-DOM()/my:myFields/my:SkillSet = "Neck-Down"

Is this the correct way to string them together?

In my above scenario, it displays the person if ANY ONE of the Skillset fields is above 75.  So if I pick "Audio" in my dropdown, it displays a person who might have "75" or greater in their "Lighting" field. 

I think I would separate them into their own filters - at least for troubleshooting. This one might be causing the problem because you have and 'and' and 2 'or's. xdXDocument:get-DOM()/my:myFields/my:SkillSet = "Breakouts" and d:Lighting >= 40 or d:Audio >= 40 or d:Video >= 40

You were right Barbara, that was the rule causing the problem.  Thanks!

 I created a column that totalled the different skill sets, and then just did a greater than on that number.  Better workaround.
