Display number parameter as text value in Formula 2

[rptg]

The Formula below contains a number parameter field that needs to function as a text value:

Stringvar s:=""; //a string to accumulate the parameter values
Numbervar i; // to use a counter
For i := 1 to count({?Read_Route})
step 1 do s:=s + ", "+({?Read_Route}) ;
ProperCase(s) [3 to length(s)]; //

The following error message returns:
"A string is required here" for "({?Read_Route}) "

Tried adding ‘to text’ like below:
step 1 do s:=s + ", "+(totext({?Read_Route})) ;
The following error message returns:
"This array must be subscripted..."

put the totext around the entire array

totext({?Read_Route})

You might want to eliminate decimals and commas, by using:

totext({?Read_Route},0,"")
