Lauren,

I would check the formula field. Your alias names in the formula need to use the ‘merge syntax’.

Your formula should look like: {{alias2}}/{{alias1}}

Here is a sample page that uses Opportunities to run the same calculation:

<skuidpage unsavedchangeswarning="" personalizationmode="server" showsidebar="true" useviewportmeta="true" showheader="true">

    <models>

        <model id="OppAgg" limit="" query="true" createrowifnonefound="false" datasource="salesforce" type="aggregate" sobject="Opportunity">

            <fields>

                <field id="Amount" name="sumAmount" function="SUM"/>

                <field id="Amount" name="maxAmount" function="MAX"/>

                <field id="PercentMaxDeal" uionly="true" displaytype="FORMULA" label="PercentMaxDeal" ogdisplaytype="TEXT" readonly="true" returntype="PERCENT" precision="9" scale="0">

                    <formula>{{sumAmount}}/{{maxAmount}}</formula>

                </field>

            </fields>

            <conditions/>

            <actions/>

            <groupby method="simple"/>

        </model>

    </models>

    <components>

        <panelset type="standard" uniqueid="sk-3iyTGX-102" scroll="">

Thank you Bill for the quick reply! That fixed the issue
Shot in the dark here…Have you had any luck displaying a UI-percentage formula like that in a chart component (like a donut chart) for %-attainment?
