I have the following gateway script: ```auto def dura(tagPath,box): tag = system.tag.readBlocking(tagPath) if tag == 2: box.props.value = tag else: box.props.value = 0 ``` Very simple script, if the tags value is equal to 2, then display 2 in a numeric entry field. Then in my project, I have a button with the following script: ```auto startTime = "[default]Timesheet/startTime" box = self.getSibling("startTime1") message.dura(startTime,box) ``` ` startTime` is the tag that is being read in the gateway script and `box` is the numeric entry field where the value 2 should be displayed. Currently, the tag does have a value if 2. So, in theory, a value of 2 should be displayed.. but a 0 is being displayed. I can read the tag in correctly in the gateway script, but every time I use the tag in a conditional statement, it seems as if the value isn't being read.. I tried to just use the value attribute of the tag, but I get an error saying > 'str' object has no attribute 'value' Thank you in advance. ---

`tag = system.tag.readBlocking(tagPath)[0].value` ---

Added this and am still getting the same result ---

You need to do some hunting then. Try logging the value and type of tag before the comparison. Add something like: ```auto # If you're running in a gateway context, this should show up on the webpage log viewer. _logger = system.util.getLogger('script debug') _logger.info(tag) _logger.info(type(tag)) ``` ---

You said **gateway** script, but you’re trying to interact with components. Exactly where is this script defined? ---

Okay, that makes more sense. Given that, I _would_ expect this variation of your original script to work: ```auto def dura(tagPath,box): tag = system.tag.readBlocking(tagPath)[0].value if tag == 2: box.props.value = tag else: box.props.value = 0 ``` What error are you getting from that, if any? ---

I am not receiving an error, the problem is that the conditional statement is returning a 0 when the value of the tag is, in fact, 2. So, the conditional statement should return a 2, rather than a 0. ---

I would then echo @zacht’s suggestion to log the data type of the value; perhaps it’s a string when you’re comparing it against an int? Python won’t do any automatic type coercion. ---

Got it, had to change it to an int.
