How to get the Maximum index count for TemplateRepeatIndex in DWT

Solution
You can solve this with the built in function: CollectionLength.
When you have a multi-valued text field "multiValuedField" you can find the item count using the following expression:
`@@CollectionLength("Component.Fields.multiValuedField")@@`
Collection Length receives an expression that is the fully qualified name of an item and a value selector of a package item.
The value returned is a string. When you need to perform an integer comparison or calculation you need to parse the value to an integer:
`@@parseInt(${CollectionLength("multivalued")})@@`
This works because the string between @@ and ${} is parsed as JScript.
Problem
I have a component in tridion where its metadata design has a field called 'list' which is populated using Categories and Keywords I used a DWT code to populate items present in the list using the following code using My DWT TBB ``` <!-- TemplateBeginRepeat name="Metadata.list" --> <!-- TemplateBeginIf cond="list" --> @@RenderComponentField('list',TemplateRepeatIndex)@@ , <!-- TemplateEndIf --> <!-- TemplateEndRepeat --> ``` but Im getting preview as one,two,three,four,five, desired output should be like: one,two,three,four,five so for this i need to get the maximum count of "TemplateRepeatIndex" Is there any inbuilt function to check the same. using Tridion-sp1,2011.
