You describe the pattern in a text string as a combination of: Combine these elements by using the string-concatenation operator &. By uncommenting the last two line in the button code, and restarting the app and loading the screen: varTempT1 is populated, other variables are empty And on one click of the button: varTempT1 and all other variables (varTempT4, varTempT5 and varTempT6) become empty, Itd be expected that no variables would be empty if RemoveIf(varTempT1 As K,true); is replaced with Set(varTempT1,Table()) or Set(varTempT1,Blank()), and the last line (Set(varTempT1,varTempT4)) is commented out, the variable varTempT1 doesnt become empty nor does code show any error.

Please note the difference with the first Concat() function; instead of just pointing out the Title column of my table, I now combine multiple attributes using the Concatenate() function (which allows you to combine multiple values) within my Concat() function: If I put that variable into a label again, the result will be as follows: Where you can convert a table into a string, you can also do that the other way around.

The resulting table has a single column, named Value. 2) On the screen that loads has a button with OnSelect code as: ForAll(Sequence(CountRows(varTempT1)), UpdateIf(varTempT1 As K,K.B=Value,{C:Mod(K.C,CountRows(varTempT1))+1}) ); Set(varTempT6,varTempT1); Set(varTempT3,LookUp(varTempT1,C=1).A); Set(varTempT4,varTempT1); Set(varTempT5,varTempT1) //;RemoveIf(varTempT1 As K,true); //;Set(varTempT1,varTempT4). To do this, you can use the With function operating on the record that Match returns: For these examples, add a Button control, set its OnSelect property to this formula, and then select the button: To see the results of MatchAll in a gallery: In an empty screen, insert a blank vertical Gallery control.

From a single Students perspective this looks like a One-to-Many relationship and we can access the information exactly as we do any other One-to-Many relationship: In CDS we can create Students and Teachers entities and relate them through a Many-to-Many relationship: In a Canvas app, lets create a screen with two galleries, one for Students: And one for the Teachers related to the selected Student, using the same One-to-Many syntax we use elsewhere: Now as we move through students, well see the Teachers list update automatically: Now lets reverse the direction and look at this relationship from the Teachers perspective: Lets duplicate our Student driven screen and have the first gallery show Teachers and the second gallery show the Students related to that Teacher: And now we can move through the Teachers and see the related Students automatically displayed: Great, we can now navigate a Many-to-Many relationship from either direction. Sorting a Filtered Table based on data in another table, PowerApps Filter gallery based on input text lookup from relational sharpoint list, Power Apps Canvas question, dueling Lookup columns, Convert Columns to Rows in collection power apps, Torsion-free virtually free-by-cyclic groups, Ackermann Function without Recursion or Stack.
