Progress bar (dxDrawImageSection)

[[XGN]Razor]

Hello, im doing a percent bar with an images, and i have an error doing the calculations, the bar looks fine at the first percents, but when reachs 100% and reset, goes to the 50% and never goes to the 0%

and when the exp grow up, the bar moves to the right.

  
sw,sh = guiGetScreenSize () 
  
function getPercent(level,expe) 
    local level = math.min(tonumber(level or 0),(#Levels-1)) 
    local needEXP = Levels[level+1] 
    return ((tonumber(expe) or 0)/needEXP) 
end 
  
function getCentPer(level,expe) 
    return math.ceil(getPercent(level,expe)*100) 
end 
  
function renderUHG() 
    local lvl = (tonumber(getElementData(getLocalPlayer(),"level")) or 0) 
    local pexp = (tonumber(getElementData(getLocalPlayer(),"exp")) or 0)+frozenMT+cachexp 
    local myper = getCentPer(lvl,pexp) 
    dxDrawImage(sw*0.0001,sh*.93,500,100,"emptybar.png") 
    dxDrawImageSection(sw*0.035,sh*.94359,myper,70,100,50,100,100,"fullbar.png") 
  

im dont know how to put fine the u,v,usize,vsize variables

What's frozenMT & cachexp?

[[XGN]Razor]

forzenMT is for changing the data

addEventHandler ( "onClientElementDataChange", getLocalPlayer(), 
function ( dataName ) 
    if dataName == "exp" then 
        frozenMT = 0 
    end 
end ) 

and cacheEXP is the exp that the player wins on an elementData, even if i delete the +frozenMT+cacheEXP the bar dont moves, only grows to both directions
