[ic] Safe: Search pattern not terminated (?)

[Michael Schwartz]

Hi,
I have a simple small code in MV4, in a page called calculate.html,  like
this:

<FORM ACTION="[process-target]" METHOD=POST>
<INPUT TYPE=hidden NAME=mv_doit VALUE=return>
<INPUT TYPE=hidden NAME=mv_nextpage value=calculate>
[seti resol]
[calc] ([value variable1] / ([value variable2] * [value variable3])) [/calc]
[/seti]
[scratch resol]

There is a </form> and input tags for vars 1,2 and 3.  Since the mv_nextpage
points to the same page, it refreshes the page, and the calculations get
done.  It works perfectly well, but I keep gettin these messages in
error.log every time the page is used:

Safe: Search pattern not terminated at (eval 211) line 1.
>
>  ( / ( * ))
>

any suggestions to stop this?  also, how can I prevent alphanumeric
characters from the user's input in the form??

Thanks


Michael
