I create a lookup table with several options base on variuos input properties, with no problem, but when I use the block the table allow me to choose the item I want but the check mark remains stuck in the custom row and does not show the check mark in the item selected. what I have to fix because I need the check mark showing the selected one, so when I create a Table it shows the item selected name instead the word custom.
As soon as one of the parameters included in the lookup table don't match a value in the lookup table it becomes "Custom".
If you don't want users to be able to get a custom value you must limit all your parameter grips to only list values that are a match with the lookup.
Check the default lengths and values of the parameters and assign a lookup with those values.
If you post the block we can always have a look at it.
