James -

Yep you have the idea.  Watch this video:  
         Update Queries

#1.  BACK UP YOUR DATA ( In case you goof up.  This is true any way but especially when making big changes.)
#2. Create a regular select query to see that you have the correct records selected.
#3. Change the query to an Update query and fill in the appropriate price field with what you want to update it to.
Example: if you want to increase PRICE by 10% the update to criteria would be PRICE * 1.1
or if you just want to increase everything by 50 cents it would be PRICE + .50

REMEMBER BACKUP YOUR DATA

Another tip:  Make a little Test DB or download Richards FREE TechHelp db (links in the video above) and play with it.

Thanks guys, I was there was a way to create a "Property-Based Service Pricing" Form that I can set pricing for the Service for all Properties by displaying the All Properties in a List or Continuous Form to set the Price?

Sorry, I'm a bit lost. Could you explain that to me like I'm a third grader. What are you wanting to do on this form? Elaborate a little more please.

Yeah, James, that doesn't make sense to us unless we know your database. See Context.

I have created a "Property-Based Service Pricing" Form that I am trying to setup for setting the Price of an Service for all Properties at once?
