When assigning a value to a variable using the "Set Variable" Action, the type of the Variable is defined based on its value.
In order to make sure that a variable is of type Text, then the value can be set as %"value"%.
If we set the value 10 to the variable %NewVar%, %NewVar% will be of type Numerical.
If we set the value %"10"% to the variable %NewVar%, %NewVar% will be of type Text.
The above can be useful in cases where a Text value, that we want it to remain as Text, it is converted automatically to another type.
For example, the "Set Variable" Action, will convert the value 1,1,1,1,1 (text) to 11111 (numerical), be default.
In order to make sure that it remains a text value, then it should be set as %"1,1,1,1,1"%.
