 Thank you in advance

As you can see, there are a bunch of possibilities here, but honestly I think most of these overcomplicate it: a!localVariables(
 local!text: "Test phrase with vowels",
 len(cleanwith(local!text, "aeiouAEIOU"))
)

Hi, Check the below code 
 a!localVariables(
 local!text: "Television",
 local!vowels: { "a", "e", "i", "o", "U" },
 local!getVowels: a!forEach(
 items: char(code(local!text)),
 expression: if(
 contains(local!vowels, lower(fv!item)),
 fv!item,
 {}
 )
 ),
 length(local!getVowels)
)

As I try to not solve every problem using a loop, here my solution: 
 a!localVariables(
 local!text: "Television",
 local!vowels: { "a", "e", "i", "o", "u" },
 count(
 union(
 intersection(
 code(lower(local!text)),
 code(local!vowels)
 ),
 tointeger({})
 )
 )
)
