Delete the end of a val

Hi there,
Is it possible to delete the end of a value ?
Exemple : Exemple : Thanks.

Hi,

It is not possible this way.
Can you give a snippet of your template to see if there is a workaround ?

I'm working in an HTML template and the php give me some values that I need to insert into the page.
I must modify the values in my HTML page.
In this exemple, I'm working with dates (real type is string) like '12 h 20 m' (val1 = '12 h' and val2 = '20 m').
I would like to format it to have an hour like '12' + ':' + '20'.
So I need to delete the end of the var if it's possible.
Thanks for the reply.

You can try [myVal;ope=max:2].
This will keep only the 2 first characters.
