how to set data store variable as block parameter variable?

Hello,

In simulink, I have created a variable Fr using the data scope memory block(also using data store read & write). How can I set this variable name Fr into sine wave block for frequency as Fr as parameter? I tried to create the parameter variable from the model editor but it ask for value. I deleted param field and write Fr there and I had to specify variable in the value which is empty [ ]. I tried writing =Fr in the value field but is not working.

Thank you

Use a Math function block. y=sin(2*pi*Fr*t), specify Clock multiplied by Fr as input and perform sin() function on it.
