I have a simple flow, in which the dim level of a light is set. Because I want to use the same level in several flows, I made a variable. Setting the level with the slider is no problem, but when I replace the slider value with a tag of the indicated variable, it doesn’t work: the level is set to 100%. What’s wrong here? ![IMG_4324](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/4/847ac8f65e05c684fbafc0af36eb92a7326ac1af.png) ![IMG_4325](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/b/0b0476537c3aa1a81cae1a515e7b2be788705dac.png) ---

Set the value of the variable to a value between 0 and 1 for 0 to 100% So 31% is fe 0.31 ---
