Show image based on variable

Question

Hello,

Im trying to show a specific image based on a variable in my survey:

[%
Begin Unverified Perl
if(GETVALUE("vMDLayout") > 1)
{
return '<img src="[%GraphicsPath()%]MDLayout1.jpg" alt="" border="0">';
}
else
{
return '<img src="[%GraphicsPath()%]MDLayout2.jpg" alt="" border="0">';
}
End Unverified
%]

But I am getting a PERL error, any ideas how I can achieve this?  Thanks

Answer 1

You are seeing an error because you are nesting Sawtooth Script like "[% [% %] %];" this is not allowed.  Instead, you need to either restructure the code to remove the nesting, or replace the inner Sawtooth Script with their unverified Perl equivalents and string concatenation.

Option 1 example:

<img src="[% GraphicsPath() %]MDLayout[% Begin Unverified Perl
if (...) {
    return 1;
}
else {
    return 2;
}
End Unverified %].jpg"/>

Option 2 example:

return '<img src="' . GRAPHICSPATH() . 'MDLayout1.jpg"/>';
