Button does not appear
In SketchPad, I created a rectangular element for a button and set its x and y coordinates using script editor to [-60, 570] and overlayed the text 'Ok' on [-10, 600] as follows.
I have to use those values because the text that I have above this button will occupy up to y = 550. This is done so that the button appears below the text.
draw rect color=gray fill=1 h=64 penwidth=1 show_if=always w=120 x=-60 y=570 z_index=1
draw textline center=1 color=black font_bold=yes font_family=sans font_italic=no font_size=32 html=yes show_if=always text=Ok x=-10 y=600 z_index=0
However, this does not render when executing in OpenSesame. What am I doing wrong?
