Hi I believe it is a dumb question. Here is what I am trying to do:

1. there is a parameter called "length_sele". I assign value of 1 to "length_sele"
2. I made an interpolation function called ttt, ttt has a value of 1 when argument is 1, and a value of 5 when argument is 2.
3. In geometry I have a cube. for the height I put ttt(length_sele). I want the height of the cube to be 1 when length_sele=1 and height to be 5 when length_sele=2.

but there is always an error. I thought it should be something related to syntax. I tried to find something on comsol.com but cannot locate an example that fixes it. Please see the attached file.

i really appreciate your help.
