Simulink controlled current source

i have from calculations made in my workspace 2 horizontal arrays. 1 represents the value the other the time that value is present. and i want my current source to use my values i saved in my workspace. if i just use a "from workspace"-block i get a "widths or dimentions"-error.

i use the build in power_battery program. and want to replace the constant that controls the current in the original file.

hope some one can help. thanks in advance
