Why move the dxDrawColorText with the name, in a nametag?

[Turbe$Z]

i added this to a nametag script:

                    dxDrawColorText (getElementHealth(player).."%", sx-w- (offset*-10), sy - (offset*5), sx, sy - (offset*-15), tocolor(255,255,255,255), textscale*NAMETAG_TEXTSIZE or (textscale*NAMETAG_TEXTSIZE)/1.5, srfont2, "center", "center", false, false, false )                    									

and for example when long the playername, the "100%" move to left direction. How to fix this?  

sorry for my very-very bad English:c
