Hey guys I've been working on making template views that change content based on provided parameters I have an accordion that i do not want to display when my view.params.apm\_id = 1 here is the binding on the display property: if ( {view.params.apm\_id} = 1, false, true ) in the designer when view.params.apm\_id = 1 the accordion is hidden but on the browser it is not any help would be greatly appreciated ---

This probably isn't the issue, but that expression can be simplified to just: `{view.params.apm_id} != 1` ---

That does simplify it, I didn't realize I could do that, thank you. However yes it didn't fix my issue ---

it shouldn't be the expression that is the issue. It works in the designer and appropriately hides the accordion when view.params.apm\_id = 1 however in a web browser it does not hide it when view.params.apm\_id = 1 designer (when apm\_id != 1): ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/2/3/2395c4c16994055d7cafbe70057b7c3fc5e2d1c7.png) designer (when apm\_id = 1, notice how steam accordion disappears): ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/d/6/d6be7a24754c812aaa0a9b0bbacd7b85e5ed40a4.png) in browser when apm\_id = 1: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/6/3697317e8a00e86a0e73adf994d2b7fa3e2483b0.png) Notice how the steam accordion is displaying in the browser when it should be hidden like the designer when apm\_id = 1?

Don't know where your parameters are coming from, but you can throw a label on the view temporarily and double check that the datatype is what you expect it to be (int vs string) ---

Maybe it's a security thing? Are you logged in on the browser as well? I noticed that your Valve Position binding is bad as well > [@Jacob\_Clark](#): > > in browser when apm\_id = 1: > > ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/6/3697317e8a00e86a0e73adf994d2b7fa3e2483b0.png) > > Notice how the steam accordion is displaying in the browser when it should be hidden like the designer when apm\_id = 1?

I wasn't evening thinking about that I pass my apm\_id parameter through the url like so ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/4/84401c1cb65a064fb713b35ec78679e8a5db6978.png) and this is the class, which would definitely explain why it doesn't work in a browser. I ASSUMED it would be automatically casted into a number but I was wrong ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/b/cb9eaa49883a2befa2cf6c9b346ebdc84d292d24.png) ---

I haven't figured out exactly what you are trying to do, but parameters are only read when the view first loads. That means that you can't use a view parameter to switch something on and off. Instead, pass in the tag path as a parameter and create a binding _inside the view_ to control whatever it is you want. ---

> [@Transistor](#): > > pass in the tag path as a parameter Are there any risks possible when allowing the user to select an arbitrary tag path to read from? Eg, they can manually change the URL to inspect any true/false tag, in theory. Probably better to have it get only part of the tag path, so you can limit the area to only one folder of tags. ---

Yes that is why I was using params, I figured out the problem and it was because it was loaded as unicode on perspective because it was a page parameter ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/4/a/4ad58dd5e5e039437d7d25fdec20e40b965ef567.png) so I just adjusted my binding to this: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/b/1bfda423ad72dfa995666045ba755913883836c9.png) and now it works in both perspective and the designer ---

Did you try the expression language's type coercion? `toInt({view.params.apm_id}) != 1`. Should be equivalent to (and faster and lighter weight than) your script transform. (It would remove the need for a transform entirely) If this is a parameter being passed in via URL I believe all URL parameters are treated as strings. ---

I would still stick with the Expression transform over Script, as they execute significantly faster. It may not matter much for such a simple expression, but it's a good rule in general. ---
