Help with Lookup Tables to Specify Visibility States

[jordanmoss1995]

Hi I work for a steel window company and I'm working on a block that uses the 'Bridge' Lookup parameter method by @Libbya for setting the amount of glazing bars in a window vertical and horizontal everything seems to work as it should however I cannot select just vertical or horizontal glazing despite having visibility states for these options the block only updates when both options have been selected I'm stuck at this point and cant find a solution any help would be greatly appreciated

@jordanmoss1995 If you're using a double lookup, never attempt to use a distance which has decimal places as you might not have enough info

eg. you might put the distance as 1800.256 but AutoCAD will see 1800.25587246

I've deleted those dimensions from your H and V and added a dimension of 1800 to both. I've also changed the lengths of both of them as well and changed your lookups so they have the correct number. You almost had it apart from those damn decimal places.
