    kavithams - Small edit in your code and it worked fine. Strange but you have to use a different variable inside a function.

     

    Before

     

    <#function replaceVal msg>
      <#assign msg = msg?replace('following ','FOLLOWING') />
      <#return msg />
</#function>

     

     

    After

     

    <#function replaceVal msg>
      <#assign repleacedText = msg?replace('following ','FOLLOWING') />
      <#return repleacedText />
</#function>

     

     

    Also, you if you want to ignore case-sensitive, you can pass another parameter  'i" as mentioned by PerBonomi

    E.g

     

    <#assign repleacedText = msg?replace('following ','FOLLOWING', 'i') />

kavithams - Can you please share dummy text which you trying to replace and couldn't replace with function?

 

I tried to replace a string using your code and it worked without any issue. 

 

 

<#assign message = "this is old value" />
<#assign message = message?replace("old","new") />

${replaceVal(message)}

<#function replaceVal message>
     <#assign message = message?replace("old","new") />
     <#return message />
</#function>

I got result "this is new value". 

 

 

You can try this function here
