How can I calculate a variable in a text
 

Hello everyone,
I started using Tecplot. I recently followed some tutorials online. To display the solution time, we insert a text: Insert > Text and we write, for example:
Time: &(solutionTime)

What if I want to evaluate a mathematical expression? say I want to calculate a variable that depends on solution time example:
myVariable = sin(solutionTime * 6.28)

is it possible?
