[solved] TypeError: a float is required
Hi
I'm getting a "a float is required typeerror" from a sequence in my experiment. The sequence consists of a Python inline script which randomizes a few elements/images that are displayed in the next sketchpad, and a "pause" sketchpad item that is identical to the first sketchpad except that it's static.
The type error seems to occus at random and I haven't been able to figure out what goes wrong. The output in the debug console isn't too helpful but I'm fairly sure that it's caused in one of the sketchpad objects.
Error message:
An unexpected error occurred, which was not caught by OpenSesame. This should not happen! Message:
a float is required
Debug console output:
Traceback (most recent call last):

Hi Benjamin,
The error is a bit ugly, because it's not properly caught by OpenSesame, but essentially it looks like you're trying to use a non-numeric value as the scale of an
imageelement in asketchpad. For example, this will trigger the error:You may also be using a variably defined scale, and have a variable with a non-numeric value. For example:
Does that solve things?

Looked through all my scale numbers and found small silly typo that made one non-numerical. Haven't encountered the error since I fixed it so that was most definitely the cause.
Thanks for the support.
