i come form hong kong so english is not good.....sorry

i have one question about the customchar,
when i use "$CustomChar(2,4,10,4,0,0,0,0,0)$Chr(158)" it can show
but when i use "$CustomChar(2,4,10,4,0,0,0,0,0)$Chr(158)$CustomChar(2,4,10,4,0,0,0,0,0)$Chr(158)" it will be error....
what is the problem??
i saw another people also have two or more customchar but also show one the clcd, but when i use more then one customchar will be show"
chr: '58)' is not a valud integer value"
