Hi all,
I started learning MobileCoach (MC) recently. Below is a question about MC that I asked and the solution I received, in case it is helpful to you 
I was trying to implement the dialogue below (lines starting with ‘>’), and encountered some unexpected relating to $participantName as shown in the screenshots below. The $participantName was not saved exactly as my input text: the input text were all converted to the lower case and symbols except for ‘-’ were all converted as “”.
“Hi I’m $coach, your digital coach.”
“What is your name?” -> free text answer option -> saving answer in $participantName
“Hi $participantName, nice to meet you!”
The image below shows the solution that my colleague kindly shared (saving the input text as ‘free text raw’ instead of ‘free text’):
Cheers~~
Best,
Jiali
