Hi everyone
**OS** : Win10
**PsychoPy version** : PsychoPy 3.0.5
**Standard Standalone?** : Yes. Using the Builder.
**What are you trying to achieve?:** I have an experiment in which I present shapes and participants have to react to them. I am trying to export this to HTML to run it online. When running in PsychoPy, it doesn’t crash. I have used to Builder to create the experiment.
**What did you try to make it work?:** After reading previous posts, I made sure that I had git installed. I also tried to export the experiment without a code component (written both in Python and Java), just to make sure it wasn’t because of that.
\*\*What specifically went wrong when you tried that?: I get the following error:
```auto
Traceback (most recent call last):
File "C:\Program Files (x86)\PsychoPy3\lib\site-packages\psychopy\app\builder\builder.py", line 1682, in fileExport

```
Any help is much appreciated!

Hi, try switching your version in Experiment Settings from ‘latest’ to 3.0.5. I suggest this because that line in my standalone relates to version parameters and I also get a logging error when using ‘latest’.

Thanks @dvbridges! that got rid of the error!
I have two further questions:
1. For randomization purposes, I have a couple of .csv files with different trial lists. At the beginning of my experiment, I randomly pick one of these .csv files with a code component (written both in Python and Java). Here’s the java snippet:
```auto
// Begin Experiment
function random_character() {
var chars = "ABCD";
return chars.substr( Math.floor(Math.random() * 2), 1);
}
condition = random_character();
```
Then, in the “condition” box of my main routine, I load the corresponding .csv file:
```auto
'design_' + $condition + '.csv'
```
When running in PsychoPy, this works fine. However, when I try to export, I get the following error:
```auto
Traceback (most recent call last):
File "C:\Program Files (x86)\PsychoPy3\lib\site-packages\psychopy\app\builder\builder.py", line 1682, in fileExport

condsPaths = findPathsInFile(params['conditionsFile'].val)

filePath = eval(filePath)
File "", line 1
'Block_' + $condition + '.csv'
^
SyntaxError: invalid syntax
```
I get that the way of calling the condition variable is not working, but, any ideas on how to properly call it?
1. If my .psyexp file is in a different drive from C:, then I get the following error when trying to import to html (the experiment runs in psychopy smoothly):
```auto
Traceback (most recent call last):
File "C:\Program Files (x86)\PsychoPy3\lib\site-packages\psychopy\app\builder\builder.py", line 1682, in fileExport

script = thisExp.writeScript(outfile, target=targetOutput, modular=True)
File "C:\Program Files (x86)\PsychoPy3\lib\site-packages\psychopy\experiment\_experiment.py", line 201, in writeScript
self.settings.writeInitCodeJS(script, self.psychopyVersion, localDateTime, modular)
File "C:\Program Files (x86)\PsychoPy3\lib\site-packages\psychopy\experiment\components\settings\ __init__.py", line 497, in writeInitCodeJS
self.prepareResourcesJS()
File "C:\Program Files (x86)\PsychoPy3\lib\site-packages\psychopy\experiment\components\settings\ __init__.py", line 486, in prepareResourcesJS
resourceFiles = self.exp.getResourceFiles()
File "C:\Program Files (x86)\PsychoPy3\lib\site-packages\psychopy\experiment\_experiment.py", line 801, in getResourceFiles
thisFile = getPaths(thisParam.val)
File "C:\Program Files (x86)\PsychoPy3\lib\site-packages\psychopy\experiment\_experiment.py", line 722, in getPaths
thisFile['rel'] = os.path.relpath(filePath, srcRoot)
File "C:\Program Files (x86)\PsychoPy3\lib\ntpath.py", line 586, in relpath
path_drive, start_drive))
ValueError: path is on mount 'C:', start on mount 'H:'
```
If I copy the folder of the experiment to C:, then I can convert to html just fine, but I was wondering if it would be possible to convert from different drives…
Thanks!

Great, I have added a [GitHub issue](https://github.com/psychopy/psychopy/issues/2327) to get this fixed for next release.
The first new error is because the dollar sign needs to start at the beginning of the line. It tells PsychoPy that this is a line of code, not that it is a variable that needs evaluating. So use:
`$'Block_' + condition + '.csv'`
Hmm not come across this error before, trying to output the html to a different drive. We could raise an issue on GitHub for this one.

thanks @dvbridges! that again solved the problem
