Dear ,

From what i know , the "" cant be used inside the username/display name .

so u could use this as a seperator for ur functions .

u could use a mixture of "MID" and "FIND" functions .

MID (FIND ("") + 1)

for ur example its like :

MID will return the subset of characters starting from an index to the end of the string .

FIND will return the index for the specificied characters .

K2:DOMAINpaul.sturmey

Finding the "" will return the index of 10

MID (10 + 1) will return the string starting from "p" to the end . which could provide u with what u need .

adding +1 is only so u dont include the "" itself.

Edited : srry i didnt notice the full transformation .

what u also need to do after that is using REPLACE function to remove the "." dot with an empty string.

which is REPLACE("." , emptystring)

after that u need to use PROPER function to get it capitalized 

PROPER ( REPLACE (MID ( Yourstring , FIND ("")) ,  "." , EmptyString ) )

Hope it helps! sorry couldnt present it through k2 studio , but hope it still helps!

Regards.

Thanks Ahmad

this worked perfectly and I'm able to get desired result
