@sojanmathew, since you are on Splunk 6.6.3 even if you have multiple rows of Results you can use Trellis Layout to Split the Single Values by Results. Even if you wanted to use two separate Single Value Panels(in case formatting options for both Single Value are different), you can use stats with eval to get Success and Failed count in Single row and then use Search Event Handler <done> or <progress> to pass on the result to Single Value Panels.
Try the following run anywhere dashboard example based on Splunk's _internal index:
(PS: I have converted log_level as per required field/value i.e. Result="Success" and Result="Failed")
<dashboard>
<label>Single Value Success And Failed</label>
<row>
<panel depends="$alwaysHideCSSPanel$">
<html>
<style>
#singleSuccess h3.dashboard-element-title, #singleFailed h3.dashboard-element-title{
text-align:center !important;
}
</style>

</row>

PS: CSS Override also has been used in the example to align the Single Value visualization Title to Center.
