Min of two values

Feels like a pretty basic question, so hopefully easy to answer! I want an input field to return the lowest value out of 1 and a numerical attribute. I.e. If the attribute is 1 or higher then the value should be 1, otherwise 0. How is this done?

The best way would be a sheet worker, but it'd hard to post code without knowing what attributes are involved - the attribute whose value you want to checkj, and the attribute where the modified value is displayed. There's a Math.max(attribute_name,1) function that would do the trick, but this only works inside a sheet worker.

Thought it must be an SW thing. The attribute with the variable value (0+) is @{armour1}. The attribute name for the minimum of (1,@{armour1}) is @{armbin1}. Much appreciated!

Try this. If your sheet doesnt have a block starting with  <script type="text/worker"> you'll need to create one that looks like <script type="text/worker"> </script> Then put the following code inside that block. If such a block already exists, use that one-  dont create a new one. on('change:armour1', () => {     getAttrs(['armour1'], values => {         let armour = +values.armour1 || 0;         let bin = Math.max(1, armour);         setAttrs({             armbin1: bin         });     }); });

Perfect, thanks!!
