How to restrict to enter only 4 digits/characters in TextBox Prompt in Cognos 8.

[joseph123]

Hi all,

I am assuming there should be some JavaScript to restrict entering length of digits/characters under Textbox Prompt in Prompt Page.
In my report I need to hide entering more than 4 digits/characters, possibly it's better if we can prompt a message saying 'Enter only 4 digits'.

Appreciate your help.

Thanks and regards,
Venkat
