Hi @Janelle_Tan
Type into accepts only string variables as input.
If you want to type into different fields then use each element of array separately using arrString(0) , arrstring(1) etc in multiple type into activities with each field that you want the data to be types into.
If those fields are similar fields or those look alike then use for each ui element and inside pass the current element to typeinto and use index variable to loop the array like this arrstring(index)
Cheers
