How to detect how many LOV values user selects on a WEBI Prompt

Question

Hello Gurus,
Is there a way to identify how many LOV Values the user selects on a Webi prompt that allows multiple value selection?
For EG: If I have a webi and there's a prompt called State on the WEBI and the user selects "Utah", "Ohio" and "Texas" from the LOV and runs the query; is there a formula I can use to get the value as 3 (no.of selections)? If that's not possible, is there a way to find out if the user has selected more than 1 value?
Thanks,
RC

Hello,
From what I know there is no direct way of figuring it out. But here is a little trick.
Create a variable to capture the user response. Lets call it - State Prompt
It should display the values like this: Utah;Ohio;Texas
Next, get the length of the response string by using the length function.
=Length([State Prompt]). It should give you 15 in our above example.
Now, create another variable [let's call it - Replaced State Prompt] where you use Replace function, to replace/remove the ";" from the response string.
=Replace([State Prompt];";";"")
Next, get the new length of the new response string by using the length function.
=Length([Replaced State Prompt]). It should give you 13 as it removed two ";".
Now, do a subtraction and add 1 to get the count.
Overall it should be something like this-
=Length(UserResponse("Enter State")) - Length(Replace(UserResponse("Enter State");";";""))+1
Hope this helps.
