Filter Function For Checkbox Field

[ConnorO2]

Currently trying to setup a filter in one of my scenarios. I've created a checkbox field that has several different values that users can select upon request time. If there is only one value selected then I would like Fusion to route it to another setup of modules. If there is multiple values selected then it would go a different route. 

What is an easy way to set this up and make sure that it reads the values?  

I know there is functions but I've not successfully setup one. 

Any help from the community would be greatly appreciated!

Currently as it is checkbox like fields read one value as a string and multiple as an array. They might be changing this soon and making it always read as an array but I don't remember exactly as I read the patch notes a while ago. 

When dealing with these fields I will just use the toString() function and use indexOf() to check for index of commas as those are what indicate array values. If its not equal to -1 then there are more than 1.

Assuming you have no commas in these fields this would work. If you do have commas, then search for either [ or ]. If they implement the change I mentioned earlier this would not work.

Also here is another approach that tells you how many items are in the array. This approach would survive the depreciation I mentioned earlier

Add value(s) to empty array,

Flatten array of arrays if more than 1 value,

Get length of array

@Lawson02 What would the filter look like after setting up this variable? 

I got the other method setup below and working but if they are going to change this I would rather set it up like this.

Replace 

with 

change filter to "Numeric Operators: Not Equal to 1". This will be your route with more than 1 checkbox field. Set a fallback, this will be your route with only 1 checkbox field.
