[JASS] Multiboard doesn't work

[VVVV]

I've created multiboard. Unfortunately it works wrong: width not changing, and icons in first row and first column aren't hide. What i've done wrong?

function MbSetStyle takes multiboard mb, integer row, integer col returns nothing
call MultiboardSetItemStyle(MultiboardGetItem(mb, row , col ), true, false)
call MultiboardReleaseItem(MultiboardGetItem(mb, row , col ))
endfunction

function Trig_MultiboardStandart_Actions takes nothing returns nothing
    // multiboard
    local multiboarditem mbi= null
    local force f = CreateForce()
    local integer a = 1
    local integer b = 1
    call ForceEnumPlayers(f, Condition(function Trig_MultiboardStandart_Func002002001001001))
    set udg_board = CreateMultiboard()
    call MultiboardSetRowCount(udg_board, CountPlayersInForceBJ(f)+2)
    call MultiboardSetColumnCount(udg_board, 5)
    call MultiboardSetTitleText(udg_board, "TRIGSTR_162")
    call MultiboardDisplay(udg_board, true)
   
    loop
        exitwhen a > 5
       set b = 1
        loop
             exitwhen b > MultiboardGetRowCount(udg_board)
            call MbSetStyle(udg_board,b,a)
            
            if a==2 then
            set mbi = MultiboardGetItem(udg_board,b,a)
                call MultiboardSetItemWidth( mbi, 0.08 )
           
            endif
            if a==3 then
            set mbi = MultiboardGetItem(udg_board,b,a)
                call MultiboardSetItemWidth( mbi, 0.021 )
            
            endif
            if a==4 then
                set mbi = MultiboardGetItem(udg_board,b,a)
                call MultiboardSetItemWidth( mbi, 0.0380 )
           
            endif
            if a==5 then
             
                set mbi = MultiboardGetItem(udg_board,b,a)
                call MultiboardSetItemWidth( mbi, 0.0450 )
            else
            endif
            if a==6 then
                     
                set mbi = MultiboardGetItem(udg_board,b,a)
                call MultiboardSetItemWidth( mbi, 0.0250 )
            
            endif
            set b = b + 1
        endloop
        set a = a + 1
    endloop
endfunction
