I am looking to update title block parameters from selected sheets. I would like to simply be able to change an instance parameter to a set value for all title blocks in a project based on a sheet selector. I started working on the script but ran into some challenges with mapping. Any assistance that can be provided would be greatly appreciated. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/2/4/24f4a86f0cf84d41ee07ffc1dbaf58f699202840.jpeg) ---

Try building a Dictionary of SheetNumbers and Titleblock ID’s > **[Dynamo Dictionary](https://dictionary.dynamobim.com/#/BuiltIn/Action/GetValues)** ---

There’s no need to even involve the Sheet. Title Blocks contain Sheet Name and Sheet Number already. Just get that information from the TB directly. No need to map anything. ---

True, but learning about Dictionaries is worth it ---

Dictionaries are great but so is understanding a problem in order to simplify or remove unnecessary steps. A dictionary could still be used with just the title block information to sort or group data without having to maintain TB lists. ---

Oh man you are right. Thank you for helping with this. For some reason I thought I had to feed in the sheet information in order to be able to select the sheets I wanted to change the parameter. I appreciate your feedback.
