Attribute	Description
VALUE	Optional value to return from a user-defined function. If no value is being returned it may be omitted.

Examples

In this example, if invalid parameters are passed to the function it returns without doing anything; otherwise it returns the sum of the two parameters.

<MvFUNCTION NAME="add" PARAMETERS="num1, num2" STANDARDOUTPUTLEVEL="html,text" >
    <MvIF EXPR="{NOT l.num1 OR NOT l.num2}">
        <MvFUNCTIONRETURN>
    </MvIF>
    <MvFUNCTIONRETURN VALUE="{ l.num1 + l.num2 }">
</MvFUNCTION>
````

Optionally, if a function does not return a value, the `<MvFUNCTIONRETURN>` tag may be omitted:

```xml
<MvFUNCTION NAME="salutation" PARAMETERS="name, title" STANDARDOUTPUTLEVEL="html,text" >
    Sincerely Yours,<br><br>
    <MvEVAL EXPR="{ l.name }"><br>
    <br>
    <MvEVAL EXPR="{ l.title }"><br>
</MvFUNCTION>
