Left Align and Right Align and others in SapScript

Hello everybody.

I am having a little problem in a SAPSCRIPT.

The problem is that I must align to right and to left some words in the same line and I don't know why this isnt working.

In text elements, I'd write the nexts lines:

/E ITEM_LINE

TS &VBDPA-MATNR&,, &VBDPA-ARKTX(34)&,,

/E ITEM_LINE_PRICE_QUANTITY

&wa_certificado-tdline(9)&,,&vbdpa-charg&,,,,&VBDPA-KWMENG(I10)&,,,, ,,

= &KOMVD-KBETR(10)&,,&v_dto(6)&%,, in the example at top).

What is my problem here? Can anyone tell me something about this?

Thank you very much.
