[Solved] Can I use a variable to store a Data Viewer Row ID?

it probably should not work that way. rowID is reserved for a unique number that is produced only when you save a value or have a prepopulated table. the rowID is not the row number. this could be why you are having issues.

perhaps this was changed or is not being named correctly in the blocks? perhaps a bug?

the call block is not accepting the created rowID. this is strange. can you report this on github?
