Hello,

I am working in ignition 7.9 and am having trouble with the system.tag.queryTagHistory function. In a tag value change script I have it scripted to pull 30 minutes worth of data from another tag and put it into a data set. However, when i try to put this data set into a table the table shows all the timestamps, but all of the cells for data are blank. Has anyone else had this issue or know what may be causing the issue?
