How it comes up with unexpected output style

[idealkindom]

With the help from #447 'replier, I use the following code to formulate some vectors, and get unxpected output style like showing in attached screenshot.The code is pasted hereafter for testing on Calcpad VM 7.1.5 portable:

#def S$(s$; qk$; j$)
'elem: <select name="targetj$">
'<option value="1;2">x=1</option>
'<option value="2;3">x=2</option>
'<option value="3;1">x=3</option>
'<option value="4;0">x=4</option>
'</select>
'<p id="targetj$" style="display:none" > Values:'s$ = ? {2}','qk$ = ? {3}*10^-6' </p> 
#post
'<span>'s$'.'qk$'.</span>
'<br/>
#end def
#pre
n = ? {5}
#hide
h = vector(n)
qk = vector(n)
Mt = vector(n)
#post
#pre
#hide
#for i = 1 : n
#post
#val
'The 'i'th elm:<br/>
#input
#pre
S$(Mt.i;qk.i;i) #{1; 2}
#show
#equ
h.i = ? {0.78}m'.
#post
#if Mt.i ≡ 4
#input
#show
qk.i = ? {5.7}*10^-6'.
#end if
#hide
#loop
#post
Mt
h
qk

Hi!

This is maybe a bug. Vectors are quite a new features and some things may need to tweak a bit more. I will look at it.
