Docx from Dynamic Template

Try doing the calculation in appian end and pass to the node

="<Project>"&
"<price>"&pv!price&"</price>"&
"<quantity>"&pv!quantity&"</quantity>"&
"<total>"&pv!price*pv!quantity"&"</total>"&
"</Project>"

Document side:

«${doc.project.price}»
«${doc.project.quantity}»
«${doc.project.total}»

Thanks for the response I have multiple values and it is CDT type 

Item1 : cost=1,quantity=5
Item2: cost=2,quantity=10

How to get 1*5 
and on next lune 2*10 value

currently I am able to get the 

Item Name |   Item Cost | Item Type | ItemQty | total Cost
A                      1                 NA                5           1*5=10
B                      10               NA                2            10*2=20

I need to get the dynamic total cost for each row.

Please suggest.

You should be able to format in foreach

<Project>
<table labelField='Table Name'>
<row index=1>
<values name='pen'/>
<values name=8/>
<values name=10/>
<values name=80/>
</row>
<row index=2>
<values name='pencil'/>
<values name=5/>
<values name=10/>
<values name=50/>
</row>
</Project>

@before-row[#list doc.project.table.row as t] @after-row[/#list]
@before-cell[#list t.values as c]
@after-cell[/#list]

a!localVariables(
local!items: {
{ item: "pen", quantity: 8, cost: 10 },
{ item: "pencil", quantity: 5, cost: 10 }
},
concat(
"<Project><table labelField='Table Name'>",
joinarray(
a!forEach(
local!items,
"<row index=" & fv!index & ">
<values name='" & fv!item.item & "'/>
<values name=" & fv!item.quantity & "/>
<values name=" & fv!item.cost & "/>
<values name=" & tointeger(fv!item.quantity) * tointeger(fv!item.cost) & "/>
</row>"
),
""
),
"</Project>"
)
)
