Using the script.currenttime as an integer

Group: Forum Members Posts: 62, Visits: 212	Hi I am having a problem whereby I want to branch in my study if the currenttime is over a certain value: e.g. <trial Blockertrial> / ontrialbegin = [values.currenttime = script.currenttime] / stimulustimes = [1=Blocker] / trialduration = 5000 / branch = [if (values.currenttime >= 11:56:01) surveypage.sliders] </trial> but inquisit is not liking the "11:56:01" part ("Expression contains unknown element or property name".) It's got me thinking - how can I use this figure with colons etc as a value? I thought that as perhaps it is a string, I could somehow remove the colons, and convert it to an integer somehow. I tried using one of the functions: replaceall("<% values.currenttime %>", ":", "") but Inquisit doesn't 'see' the value rather just the actual characters (the greater than sign, the percentage sign and the letters) Would greatly appreciate a response on this as I'm up against a deadline and can't figure this out! Thanks in advance

Thanks in advance This should do the trick: <values> / currenttime = 0 </values> <block myblock> / trials = [1=Blockertrial] </block> <trial Blockertrial> / ontrialbegin = [values.currenttime = script.currenttime; values.currenttime = replaceall(values.currenttime, ":", ""); ] / stimulustimes = [1=Blocker] / trialduration = 5000 / branch = [if (values.currenttime >= 115601) surveypage.sliders] </trial> <text blocker> / items = ("This is the blocker trial.") </text> <surveypage sliders> / caption = "This is the slider page." </surveypage>

This returns an integer representing the number of milliseconds elapsed since the trial started, and is generally what we use for dynamically setting time limits and criteria. In that case, your code would look something like the following (assuming a 10 second criterion): <trial Blockertrial> / stimulustimes = [1=Blocker] / trialduration = 5000 / branch = [if (trial.Blockertrial.elapsedtime >=10000) surveypage.sliders] </trial> -Sean Edited 6 Years Ago by seandr
