Context Variable to Character and map new value and back to variable

[Vignesh5.r]

In Ca Layer 7 , i  have a variable "String" . I need to split this variable by each character, then look up the character in "map value " and extract the new value    and then merge all the new values as a String. 

Is this something that is possible? 

 

For example

 

Input  :  Test

under map value, i have defined below alues 

T -> 2

e ->3

s  -> 4

t - >5

 

So now , my expected output in a variable should be  2345 .

 

Any ideas on how we can get this done ?
